In this tutorial, we are going to write a C program to evaluate the equation s=sqr(a()+b()) using function in C Programming with practical program code and step-by-step full complete explanation.
C program to evaluate the function equation.
#include<stdio.h>
#include<conio.h>
void main()
{
int s=0,a(),b(),sqr(int);
clrscr();
s=sqr(a()+b());
printf("Square of sum=%d",s);
}
int a()
{
int a;
printf("Enter value of a:");
scanf("%d",&a);
return(a);
}
int b()
{
int b;
printf("Enter value of b:");
scanf("%d",&b);
return(b);
}
int sqr(int x)
{
return(x*x);
}
Output
Enter value of a: 5 Enter value of b: 3 Square of sum = 64
