WAP of C Language that illustrates the Function with no Arguments and Return values

Functions with no Arguments and Return value:

The called Function does not recieve any data from the calling Function. It is also a one-way data communication between the calling Function and the called Function. So let us understand this with the help of Program:

Statement of C Program: This Program illustrates the Function with no Arguments and Return values:

#include<stdio.h>

#include<conio.h>

void main()

{

float sum;

float total();

clrscr();

sum = total();

printf(" Sum = %f\n" , sum);

}

float total()

{

float a, b;

a = 5.0 ;

b = 15.0 ;

return(a+b);

}

Output:

Sum = 20.000000

                                                                    That's All
