C Programming Language

Before learn C language, we would learn about what is program. A program is a set of instructions to perform any task. Computer program is written in high level language. The entire process is done by a program called compiler. C is a high level language that developed by Dennis Ritchi in 1972.

There are three types or programs:

1. Sequential

2. Conditional

3. Iteration

Common structure of C Program:

# include <stdio.h>

#include <conio.h>

Void main()

{

clrscr();

printf(“Hello World”);

} ——- End Program

# include <stdio.h>

#include<conio.h> : This section is in processed form which helps in functionality of program.

Void : It means nothing

Main : Each C program start with main function. This is origin of program. By default function is desiged to return any value, if a function does not return any value it is prefixed with void.

{} ( “Curly braces”) : These are used to define block of program. { : Start of program } : End of program

Clrscr(): This is a function. Function always end with simple baces(). This function is used to clear screen. The working of this function is written in conio.h header file.

Printf(): This function is used to print any message on screen. The working of this function is written in stdio.h header file.

;(Semi colon): Each c statement is terminated with semicolon.
