WAP of C Language that calls many Functions

Statement of C Program : This Program prints the Messages or Instructions when different Functions calls: 

#include<stdio.h>

void England();                                      /* Function declaration */

void Australia();                                     /* Function declaration */

void India();                                           /* Function declaration */

int main()

{

printf(" I am in main\n");

England();                                                 /*  Function call */

Australia();                                                /*  Function call */

India();                                                      /* Function call */

return(0);

}

void England()                                             /* Function definition */

{

printf(" I am in England\n");

}

void Australia()                                             /* Function definition */

{

prinf(" I am in Australia\n");

}

void India()                                                   /* Function definition */

{

printf(" I am in India\n");

}

Output:

I am in main

I am in England

I am in Australia

I am in India

Note:  Number of Conclusions drawn from the above Program:

• A C Program is a collection of one or more Function or you can say A Function is a basic building block of C program.

• If a C program contain only one Function, then it must be main(), because Program execution always begins with main().

• In C program, as many number of Functions exist i.e there is no limit on the number of Functions.

• Control returns to main() after each Function has doing its work or thing.

• The Program ends, when main() runs out of statements and Function calls.
