Calling Multiple Functions
If you have grasped the concept of ‘calling’ a function you are prepared for a call to more than one function. Consider the following example:
Example
#include<stdio.h>
int main( )
{
int num;
printf("Enter number ");
scanf("%d",&num);
printf("Square is %d",square(num)); // calling function square
printf("\nCube is %d",cube(num)); // calling function cube
// calling function toThePowerFour
printf("\nPower to 4 is %d",toThePowerFour(num));
getchar();
return 0;
}
int square(int number)
{
// returning a value from function to the calling block
return number*number;
}
int cube(int number)
{
return number*number*number;
}
int toThePowerFour(int number)
{
return number*number*number*number;
}
