TYPES OF SOFTWARESoftware is a set of electronic instructions that tells the computer how to do certain tasks. A set

of instructions is often called a program. When a computer is using a particular program, it is said to be running or executing the program.

The two most common types of programs are system software and application software.

System Software

System software exists primarily for the computer itself, to help the computer perform specific functions.

One major type of system software is the operating system (OS). All computers require an operating system. The OS tells the computer how to interact with the user and its own devices. Common operating systems include Windows, the Macintosh OS, OS/2, and UNIX .

When we turn on a computer, it goes several steps to prepare itself for use. The first step is called the power-on self test (POST). The computer identifies the devices attached to it, identifies the amount of memory available, and does a quick check to see whether the memory is functioning properly.

Application Software

Application software tells the computer how to accomplish tasks the user requires, such as creating a document or editing a graphic image.

Some important kinds of application software are:


Some important kinds of application software are: MS-OFFICE, TALLY, etc

STRING LENGTH

Aim : To find the Length of the String using and Without using the String function.

Algorithm :

Step 1: StartStep 2: cnt0Step 3: read strStep 4: lenstrlen(str)Step 5: write lenStep 6: for i0 repeat until str[i]!=’\0’ Step 6.1: cntcnt+1 Step 6.2: ii+1Step 7: write cntStep 8: Stop

COMPARISION OF STRINGS

Aim :To write a program to Compare two strings without using string function.

Algorithm :

Step 1: StartStep 2: read str1,str2Step 3: for i0 repeat until (str2[i]!=’\0’) Step 3.1: if (str1[i]=str2[i]) then, ii+1 otherwise, Step 3.1: write “strings are Not Equal” Step 3.2: goto step 5 Step 4: write “strings are Equal”Step 5: Stop.

53

Flow Chart :

Start

Read Str1, str2

For i 0 to (str2[i]!=’\0’)
