explain c program with some examples.

Explanation of some basic commands in C programming to write basic C Program:

Below are few commands and syntax used in C programming to write a simple C program. Let’s see all the sections of a simple C program line by line.


1. #include <stdio.h> :  This is a preprocessor command that includes standard input output header file(stdio.h) from the C library before compiling a C program.

2 int main() : This is the main function from where execution of any C program begins.

3 { :  This indicates the beginning of the main function.

4. /*_some_comments_*/ :  whatever is given inside the command “/*   */” in any C program, won’t be considered for compilation and execution.

5 printf(“Hello_World! “); : printf command prints the output onto the screen.

6 getch();  : This command waits for any character input from keyboard.

7 return 0; : This command terminates C program (main function) and returns 0.

8 } :  This indicates the end of the main function.



C Basic Program:

#include <stdio.h>
int main()
{
/* Our first simple C basic program */
printf(“Hello World! “);
getch();
return 0;
}    


Output:

Hello World!
