Part-B (Questions carrying 4 marks) Chapter 2 (Strings)

1 What is special about the array of char? Ans: char arrays have special importance in C Language. There is no data type in C to store strings. Therefore, to store string data in, char arrays are being used in C language. To store strings in C, we have to declare char arrays. For example:

char city[20]; In this example, char array named city has been declared which can store city name with maximum of 20 characters. 2 What is string? Ans: String is a combination of one or more characters. It is always enclosed in double quotes. They are terminated by null character (\0) in c. To store strings in c, we use char array. For example:

char city[20]; It declares a string variable named city. It can store the string of maximum 20 characters. Consider another example:

char city[20+=”Sunam\0”; It initializes a string variable named city of length 20 and stores “Sunam” as string value. This value is terminated with null character ‘\0’. 3 What is the purpose of the null character? Ans: Null character is also called empty character. It can be represented with the symbol ‘\0’. The length of null character is C is zero. Null character is used to terminate the string in C language. For example:

char city[10]= “Sunam\0”; It declares a string variable named city of length 10 and stores “Sunam” as string value. This value is terminated with null character ‘\0’. Q4: Give the declaration for a string called student, which holds up to 50 characters. Show two ways to initialize the string in the declaration? Ans: String declaration for student with 50 characters is:

char student[50]; Two methods for declaring strings are:

char student[50+=“Ram\0”; char student[50]=,‘R’, ‘a’, ‘m’,’\0’-;

Q5: What is the limit of char array? Ans: Char arrays have a special importance in C language. There is not primitive data type to store string data in c. therefore, to store string values in c, we have to use char arrays. Limit (length) of char array defines the length of string. In c clanguage, maximum length of a string in char array can be 65535. Therefore, we can not extend the limit of char array more than 65535.

Q6: What is a difference between “A” and ‘A’? Ans: “A” is a string while ‘A’ is a character. “A” is string because any string value must be enclosed in double quotes and ‘A’ is char because any char value must be enclosed in single quotes in c language.

Q7: Give the difference between putchar() and puts()? Ans: The difference between putchar() and puts() functions is as follows: puchar() function: This is the unformatted character output function. This function is used to output a single unformatted character on the monitor screen. puts() function: This is the unformatted string output function. This function is used to output an unformatted string on the monitor screen.

Q8: List the various functions that can be used to perform the I/O of the string data? Ans: A string can be read-in or written-out using the input/output functions. Some of the commonly used string input/output functions are explained below: Reading Strings (String Input Functions):

scanf() : This function is used to input single word formatted string

gets() : This function is used to input multiword unformatted string

getchar() : This function is used to input unformatted single character Writing Strings (String Output Functions):

printf() : This function is used to output formatted string

puts(): This function is used to output unformatted string

putchar(): This function is used to output unformatted single character



Q9: Can we use scanf() to read a string? If no, then give reason. Why it is wrong to use the & symbol when reading in a string with scanf()? Ans: Yes, we cam use scanf() to read a string. But this function can not be used to inpute multiword strings in C language. There is not data type for storing string data in C. For this, we use char arrays. Name of an array in C represents the address of the first element of array. So, when we use char array in scanf() function, array name itself represents the address of string variable. So, it will be wrong to use the & symbol when reading a string with scanf() function.

Q10: What is stored in the str, if each of the following values, separately, is read in using a single call to scanf()? char str[10];

a) cityscape Ans: cityscape b) New Delhi Ans: New c) one or more blanks Ans: one

Other Important Questions

Q:1 Explain strlen() function with suitable example. Ans: Function strlen() stands for string length. This function is used to count the total number of characters in the

given string. This function is present in the string.h header file. Therefore, to use this function, we have to include

the string.h header file in our program. Following code shows how to use this function:

strlen(“punjab”);

This function returns 6 as string length because the string “Punjab” contains 6 characters.

Q:2 Explain strrev() function with suitable example.

Ans: Function strrev stands for string reverse. This function is used to reverse the given string value. This function is

present in the string.h header file. Therefore, to use this function, we have to include the string.h header file in our

program. Following code shows how to use this function:

strrev(“Punjab”);

It reverses the given string to bajnuP.

Q:3 Explain strcpy() function with suitable example.

Ans: Function strcpy stands for string copy. This function is used to copy a string value into string variable. This

function is present in the string.h header file. Therefore, to use this function, we have to include the string.h header

file in our program. Following code shows how to use this function.

strcpy(str, “Punjab”);

It copy/store the string value “Punjab” into the string variable str.

Q:4 Explain strcat() function with suitable example.

Ans: Function strcat stands for string concatenation. This function is used to combines the two strings. It appends

2nd string value at the end of first string value. This function is present in the string.h header file. Therefore, to use

this function, we have to include the string.h header file in our program. Following code shows how to use this

function. Let the two strings are:

char str1*10+=“Sunam”;

char str2*10+=“City”;

strcat(str2, str1);

It adds value of str1 at the end of str2 and make it - CitySunam

Q:5 Explain strcmp() function with suitable example.

Ans: Function strcmp stands for string compares. The strcmp( ) function is used to compare two strings. It returns

one of the three possible values: zero, negative, or positive. It uses ASCII value of characters to compare strings. The

function strcmp() is present in the string.h header file. Therefore, to use this function, we have to include the string.h

header file in our program. Consider the the following example:

If ASCII values of 1st string is equal to ASCII values of 2nd string, It returns 0

e.g. strcmp(“punjab”,“punjab”) returns 0

If ASCII values of 1st string is less than the ASCII values of 2nd string, It returns negative value

e.g. strcmp(“india”,“punjab”) return –ve value

If ASCII values of 1st string is greater than ASCII values of 2nd string, It returns +ve value

e.g. strcmp(“punjab”,”india”) return +ve value



Q:6 Explain strupr() function with suitable example.

Ans: Function strupr stands for string upper. This function is used to convert the given string into Upper case (i.e. in

capital letter). This function is present in the string.h header file. Therefore, to use this function, we have to include


strupr(“Punjab”);

It converts the given string into PUNJAB.

Q:7 Explain strlwr() function with suitable example.

Ans: Function strlwr stands for string lower. This function is used to convert the given string into lower case (i.e. in

small letter). This function is present in the string.h header file. Therefore, to use this function, we have to include


strlwr(“PUNJAB”);

It converts the given string into punjab.

Q:8 Explain atoi () function with suitable example.

Ans: Function atoi stands for ascii to integer. This function converts the string number into integer value. This

function is present in the stdlib.h header file. Therefore, to use this function, we have to include the stdlib.h header

file in our program. Consider the following example:

atoi(“456”);

It will convert the string number “456” into integer value 456.

Chapter – 3 (User Defined Functions)

Q1 Distinguish between arguments and parameters? Ans: These are variables used in function. These are the optional part of the function. Their existence depends on the

requirement of the user. It means there may be zero or more arguments. These arguments are of two types:

Arguments: Variables used in a function call are called arguments. These are written within the parentheses ( ) after

the function name in the function call. They are also called actual parameters.

Parameters: Variables used in the function definition are called parameters. They are also called formal parameters.

They receive values form the calling function. Parameters must be written within the parentheses ( ) after the

function name in function definition.

Q2 What is the need of function declaration? Ans: Function declaration is also called Function Protoyping. It is different from function definition. It does npot have any body. It is terminated with semicolon (;). Function declaration provides the information to the compiler about the type of function, its name and arguments. When we call a function to use it, compiler verifies the function call with its declaration. If function declaration does not found, compiler will display an error message. Q3 How does a function definition differ from function declaration? Ans: Function declaration is also called Function Protoyping. It is different from function definition. It does npot have any body. It is terminated with semicolon (;). Function declaration provides the information to the compiler about the type of function, its name and arguments. When we call a function to use it, compiler verifies the function call with its declaration. If function declaration does not found, compiler will display an error message. Function Definition defines the working of the function. In the definition of a function, we define the type, name, arguments and body of the function. Q4 What role does the return statement play? Ans: Rerurn is a keyword. It is used in the definition of functions. This keyword is used in those functions which return a value to their calling function. Return statement must be the last statement in the body of the function. For example:



int sum(int a, int b) { int c=a+b; return c;

} In the above example, the function sum() returns the value of c to its calling functions with the help of return statement. Q5 When will the execution of the function terminates? Ans: Function is the logical grouping of statements. Functions are used to solve a complex problem by dividing it into smaller parts. A function once defined can be used many times. When a function is called, it starts its execution. This execution goes on till the end of the body of the function. When function completes its execution, program control is returned to the calling function. Q6. Explain the advantages or uses of function? Ans: Using functions have a number of advantages. The main advantages of using a function are:

It becomes easy to solve a complex program by dividing it into small functions.

It becomes easy to debug the program.

It is easy to maintain and modify a function.

It allows the reusability of code. A function can be called any number of times but defined only once.

Small functions are self-documenting.

It allows the programmer to build a library of the commonly used functions.

It facilitates top-down modular programming approach.

Other Important Questions Q1. What are functions? Write their types. Ans: A function is a subprogram. It is also called a Routine or Procedure. It is a logical grouping of statements in a program. Functions are used to solve a complex problem by dividing it into smaller parts. A function once defined can be used many times. In every executable programs, there must be a main() function in the program. Program execution starts from this main function. In other words, we can say that main function act as a entery point of execution on the program. Types of Functions: Functions can be classified mainly into two categories:

1. Library or Built-in functions 2. User defined functions

Q2. What are Library Functions? Ans: Those functions, which are in-built or pre-defined in the C language, are called standard or library functions. All these functions are organized in header files (also called library files). To use any library function, we must include the corresponding header file (in which it is defined) in our program. For example: clrscr( ), printf(), scanf(), sqrt(), strcpy() etc. are the predefined functions. The input output functions scanf( ) and printf( ) are defined in the stdio.h header file. So, we have to include this file in our program if we want to use these functions. Similarly, string functions strlen( ), strcpy( ), strcat( ), strcmp( ), strupr( ), strlwr( ) etc. are defined in the string.h header file. So, we must include string.h header file to use these string functions in our program. Q3: What are User Defined Functions?

Ans: Those functions, which are defined by the user, are called user defined functions. User can define his own

functions to fulfil his requirements. The function main() is an example of user defined function. Its body is defined by

user.

Q4: What are Storage Classes? Storage classes are used to define the scope, life and location of a variable in the program. In C, four storage classes are used to define scope, life and location of variable. These are: 1. Automatic Variables 2. Register Variables 3. Static Variables 4.External Variables



Chapter-4 (Window Movie Maker- I) Q1. What is the use of Windows Movie Maker Software? Ans: Windows Movie Maker is a video editing program. Window Movie Maker is a part of Windows XP. We can also

download it from Microsoft’s Windows Website. Movie Maker allows user to combine photographs, video-clips and

sounds to create a movie. Titles, transitions, and effects can also be added to movie to make it professional. Movies

created through Windows Movie maker can also be played on Computers and Movie players. These movies can also

be shared online.

Q2. What are the options in Movie tasks pane of Windows Movie Maker? Ans: Task pane and collection pane are present at the left side of the Window Movie Maker

Interface. Only one of them will appear at a time. If task pane does not appear, click on the

Tasks button on toolbar to display it. This pane shows the common tasks that are used for

making a movie. This pane provides the following three categories of the tasks:

Capture Video: It provides options to import videos, pictures, and audio files to our collection to create a movie.

Edit Movie: It provides options for editing a movie. We can view and add video effects, transitions, and titles to our movie. We can also use Auto Movie to begin making a movie automatically.

Finish Movie: It provides options for saving our final movie. We can store these movies on our computer, on a CD, or send it via an e-mail etc. We can also send to a DV camera.

Q3. What is the use of “Create clips for Video files” of ‘Import Video File’ option? Ans: When we click on the Import Video opetion in the Task pane, a dialog box will appear. This dialog box has the option of ‘Create clips for Video Files’ with a checkbox in the lower part of the dialog box. If option ‘Create clips for videos files’ is checked, then it

will import the selected video file by splitting it into

smaller clips.

If option ‘Create clips for Videos files’ is not checked,

than the selected video file will be imported as a single

video file in our project.

Q4. What is the difference between clip and Videos? Ans: Clip is formed by dividing a video into smaller parts. Size of a video file is much larger as compared to a clip. Time duration of a video is also larger than a clip. We can combine many clips to create a single video file. In windows movie maker, we can create a video by combining clips and can also divide a video into smaller clips easily. Q5. Show by example how will you use Button “Take Picture of Monitor”? Ans: “Take Picture of Monitor” is available on the Monitor componenet of the Window movie maker interface. This

button is used to capture a frame of a video as a picture. This captured frame is also called screenshot. This captured

frame can be saved into our computer system. To take a picture from video in the monitor, we can use the following

steps:

1. In the Contents pane, select the video clip from which we want to capture a picture.

2. Under the monitor, move the slider (seek bar) to that position from where we want to capture the picture.

3. Click the Take Picture button on the monitor.

4. Save Dialog box will appear to save the captured frame. Enter a name for the picture file, and then click the

Save button.

Chapter-6 (Concept of Networking)

1. What is a Network? Ans: Computer network is an interconnection of two or more computers to share resources (hardware, software or

data). These computers are connected with each other using some communication medium. These communication

medium can be wired (twisted pair cable, co-axial cable, fibre optics etc.) or wireless (Bluetooth, infrared etc.) There

is no limit to the distance between computers in a network.



2. Name the devices that are used to connect a computer to an analog telephone lines. What are its different types? Ans: It is the Modem that is used to connect a computer to an analog telephone lines. These modems are of two types: External Modem and Internal Modem.

External Modem: It is a seprate device from the computer. It is connected with serial port COM1 or COM2 of the computer. These modems are more expensive than the internal modems. But these modems are faster then the internal modems.

Internal Modems: It is a printed circuit board. It is attached in the system unit. These modems are cheaper then the external modems. These modems are also slower then the external modems.

3. Define the term communication channel? Ans: Communication Channels are also called Communication Media. Communication channels are those channels which are used to transfer data from one computer to another in a network. Communication channels are of two types: Guided Media and Unguided Media. 4. What is network topology? Ans: Network topology is the arrangement of the various elements (links, nodes, etc.) in a computer network. Computers can be connected in different ways in a network. So there are different types of topologies. Commonly used topologies are Bus topology, ring topology, star topology, mesh topology and tree topology. 5. What is URL? Ans: Each web page on the web has a unique name or address. This name or address is called Uniform Resource

Locator. To access any webpage on the internet, we have to type the URL of website in the web-browser. Example of

URL is:

6. What is WWW? Ans: The World Wide Web is also called www or web or W3. It is a system of web servers. In www, information is

stored in the form of web-pages. Web pages are written in HTML (Hypertext Mark Language). HTML defines the

structural elements of web page. A web-page contains text, picture, audio, animations etc. The collection of related

web-pages is called a website. Websites are stored on the web-servers. The web-pages of a website are linked with

each other. These links are called hyperlinks. By default, hyperlinks are shown in blue color with underline. The first

web-page of a website is known as Homepage.

Each web-site/page has a unique address. This address is called URL (Uniform Resource Locater). Example of URL is:

www.google.com. To use these web pages, we have to use Web browsers. Some popular web browsers are Google

Chrome, Firefox and Microsoft's Internet Explorer.

7. What is internetworking? Ans: When two or more computer networks are connected with each other, it is called as computer internetworking. To inter-connect different networks, various types of devices are used such as router, gateway etc. 8. What is FTP and what are its uses or advantages? Ans: It is a standard Internet protocol. These protocols are used to exchange files between computers on the Internet. FTP uses the Internet’s TCP/IP protocols to exchange files. It’s also commonly used to download programs and other files to our computer from other server computers.

9. What is a network hub and what are its uses or advantages? Ans: Network hub is a communication device which is used to create a network. It is used to connect two or more Ethernet networks. After connecting networks with it, it represents the neworks as a single network. A hub can receive input from many lines. When hub receives input from any of the input lines, it sends the received data to all other lines of hub. Hubs are commonly used in the Star Network topology. 10. Define the term Data Transfer Rate. What are its units? Ans: The transfer of data from one computer to other is called data transfer. The amount of data that can be

transferred from one computer to another in a given time period (usually a second) is called Data Transfer Rate.

Data transfer speed is expressed in bits. Units of data transfer rate can be:

kbps - kilo bits per second

mbps - mega bits per second

gbps - giga bits per second

tbps - tera bits per second

11. What do you understand by the term Transmission media? Ans: Communication Media is also called Communication Channels. Communication channels are those channels which are used to transfer data from one computer to another in a network. Communication channels are of two types: Guided Media and Unguided Media.

Chapter-8 (E-Governance)

Q1. What do you understand by JIT? Ans: JIT stands for Just In Time. E-governance can be used anywhere anytime. In older manual systems, the working timing of offices are fixed. Before or after these fixed timings, working in offices is not possible. But now a days, it becomes possible to do work related to these offices at anywhere anytime with the help of e-governance and internet. For example: earlier, the depositing and withdrawal of money in banks was possible only during the banking hours. But, now with the arrival of ATM, we can deposit and withdraw the money at any time. Such types of systems are also called JIT (Just-in-time). Q2. What is i-ticketing? Ans: The term i-ticket stands for internet-ticket. It is a paper-ticket which we can buy through railway’s website. During booking of i-ticket, we specify the journey details, passenger information, and pay online. The ticket is sent through courier to the delivery address specified in 2 to 3 days. This is the same as the ticket that we get when we buy from a railway booking counter. Limitations of i-ticketing:

We cannot cancel this ticket online. To cancel the ticket, we have go to railway booking counter at railway station.

We have to buy i-ticket at least 3 days before the journey date. We can not book it instantly. Q3. What is e-ticketing? Ans: The term e-ticket stands for Electronic ticket. It is a digital ticket. E-ticketing is booked according to the time table of a train. For booking of e-ticket, we will have to provide the details of identity proof e.g. PAN card, Voter ID card, Driving License, Passport or Aadhar card. After that, we take the print-out of our ticket. During journey we have to keep this print and identity proof with us. For payment of tickets, we can use internet banking or debit cards or credit cards etc. We can also cancel this ticket online. We can book these tickets just before our journey. Q4. Write the importance of e-governance? Ans: Now-a-days e-governance is being used almost in every field, i.e. in education system, business, medicinal facilities etc. Now every city has e-governance, Suwidha and public-relation (Sampark) centre that provides many facilities to citizens. E-governance is of a great importance because it provides many benefits to citizens of India. Some of the common benefits of e-governance are listed below:

Low cost: The starting expenditure in e-governance is slightly higher. Once, the system set-up then the daily recurring cost becomes very economical.

Fast Speed: In e-governance, the works are performed at a much higher speed. For example: to book the rail ticket in the earlier time, we had to travel to the railway station but now everything is available on the web site of railway. We can now book the railway ticket through the computer while sitting at home. Like this net-banking is another example which uses e-governance.



Anywhere anytime: In older manual systems, the working times of offices are fixed e.g. earlier, in any bank, the depositing and withdrawal of money was possible only during the banking hours. But, now with the arrival of ATM, we can deposit and withdraw the money at any time. This type of procedure is also called JIT (Just-in-time).

Easy management: With the introduction of e-governance, the procedure of management has become very easier. It has also helped in bringing the transparency in the working system of the government.

Q5. Describe main uses of Suwidha Centres? Ans: Some of the common uses of Suwidha Centres are given below:

1. We can purchase affidavits from the Suwidha Centers. 2. Facility of attestation of affidavits is also available at Suwidha Centers. 3. We can also apply for birth/death certificates at Suwidha Centers. 4. We can also apply for passports at Suwidha Centers. 5. We can also apply for licence of weapons at these centers. 6. Aplications for renewable of licences can also be applied at these centers. 7. Application for the registration of vehicle is also submitted at these centers. 8. Electricity bills can also be paid at these centers. 9. Applications for marriage certificates can also be applied at these centers.

Other Important Questions Q1. What is E-Governance? Ans: E-governance refers to any government functions or processes that are carried out in digital form over the internet. It may be said that it is a use of information technology by the government agencies. These technologies can serve its users for better delivery of government services. Local, state or central government, setup sites from which the citizens can find information, download forms and can contact government officials or representatives. Examples of e-governance are: filing taxes online on government sites, applying for passport etc. Q2. What is Internet Banking? Ans: Internet banking had changed the entire system of banking. In the areas of banking institution, it is the start of a

new age. In the earlier times, all kinds of banking operations were possible only by visiting the banks. But now a

days, many types of banking operations can be done by just a click of mouse using internet banking. Internet banking

can be seen in the following representation:

24 hourly knowledge to customer about his account

Payments or transferring of money from one account to another account

On-line operating of own debit or credit cards

To give the information of new bank schemes on the internet

Providing security to the customer’s accounts Q3. Write the different areas of e-governance. Ans: Presently, e-governance is being used in almost every field. For e-governance, a large part of the budget is being

approved by the government every year. Following are the some of the main fields in which e-governance services

are being provided:

Internet Banking

On-line booking of Rail & Air Tickets

Functioning of Passport Office

On-line Business

Payment of taxes

Payment of water and sewerage bills

Payment of electricity bills

Payment of telephone bills
