Aim: Write a program to evaluate the series 1^2+2^2+3^2+……+n^2.

Code:

//For turbo C++ remove below comments
#include <stdio.h>
//#include<conio.h>
void main()
{
    int n,sum,i;
    printf("Enter number : ");
    scanf("%d",&n);
    sum=(n*(n+1)*(2*n+1))/6;
    printf("Series : ");
    for(i=1;i<=n;i++)
    {
        if(i!=n){
            printf("%d^2+",i);
        }else{
            printf("%d^2=%d",i,sum);
        }
    }
    // getch();
}

Output:
