PREFACE

Hi, Dear Reader..... How are u? I hope you are fine.

I am good, thanks for asking.

A book is a writer's child. I made this one with great efforts.

Thanks for investing in this book and I am sure you will get a

good return.

This book is meant for all those people who want to start from

basic and learn the art of programming in c language. I will be

highly obliged if you message/mail me you feedback or

suggestion on +91-9671878677 (Whatsapp only) or on

[email protected].

How to use this book?

In this book, you will find a collection of 50 programs which are

being asked in almost every interview related to C

programming. After practicing these 50 programs you will see

the improvement in your programming skills and also in your

confidence. By learning these 50 programs one can easily

crack any interview based on C programming language.

You will find an explanation for each and every program in a

very simple manner just go through the program and try to

develop a logic after that see the output and try to figure out the

different path of execution and then finally see the explanation

of the program which helps you to get complete insight about

the program.

I wish you all the very best for your journey of learning the C

programming language.

“GOOD LUCK”

ACKNOWLEDGMENTS

Writing a book is harder than I thought and more rewarding

than I could have ever imagined, none of this would be possible

without the blessings of my parents and elders.

I want to thank my parents Dr. Pawan Kumar Sharma

(Associate Professor, Government of Haryana) and Mrs.

Sushma Sharma who always stood by my side and supported

me emotionally as well as financially.

I want to thank GOD for helping me through every phase of my

life. I truly believe that anything can be achieved with the help

of GOD.

In the end, I want to thank EVERYONE who ever said anything

positive to me or taught me something. I heard it all, and it

meant something.

1. PROGRAM TO PRINT “HELLO WORLD”:

Program:

#include<stdio.h>

#include<conio.h>

int main()

{

clrscr();

int num; //variable declaration with int data type

printf("\n\t\t\t Hello World! \n\t\t Welcome to the world of \n\t\t\t

C PROGRAMS\n");

printf("\n\n\t\t\tWriter : Deepak Sharma\n\n\n");

getch();

return 0;

}

Output:

Explanation:

In this program we are printing some text on the screen using printf

statement.

#include<filename> is simply preprocessor directive which is used

for file inclusion. Using #include perprocessor directive we can

simply reuse the contents of one file in to another like functions,

variables etc.

#include<stdio.h> header file used for standard input and output

operations. This is used to take input from keyboard and displaying

output on screen. #include<stdio.h> contains functions like printf

and scanf.

#include<conio.h> header file used for console input output

operations. This header file contains functions such as getch(); and

clrscr();

int main(); Main function is the essential part of any c program

because execution of every c program starts from main function.

clrscr(); This is a predefined function of conio.h This function is

used to clear the previous output on the output window.

printf(""); This is a readymade predefined function used for

printing on the output window.

\n: New line character used for advances the output to the next line

equivalent to pressing the enter key on keyboard.

\t: Used for tab spacing between the values equivalent to pressing

the tab on keyboard.
