The C program's structure is as follows:

 

1)Documentation:

 consists of a statement that describes the programme or programmer, the issue, etc.

   Ex:

   /*Prog for addition of two no */

 

2)Link Section:

   For a compiler to link a library function from a function.

  Ex:

  #include<stdio.h>

  #include<conio.h>

 

3)Definition Section:

   Define all symbolic constant.

   Ex:

   void()

 

4)Global Declaration Section:

    For designating a variable as a global variable that can be accessed by all programme functions.

     Ex:

     int a=10;

 

5)Main Function Section:

  This is the most crucial section of the programme. It includes the program's declaration and execution portions.

    Ex:

    main()

    {

      clrscr();

       Printf("Hello!");

    }

 

6)Sub Program Section:

   This include user define function. This function are placed after the main function.
