/*25. Write a program to evaluate the series 1^2+2^2+3^2+……+n^2*/

#include <stdio.h>
#include <math.h>
int main(void)
{
    int n, sum = 0;
    printf("\nEnter the number which you wanted the series:");
    scanf("%d", &n);
    printf("\n0^2");
    for (int i = 1; i <= n; i++)
    {
        printf(" + %d^2", i);
        sum = sum + pow(i, 2);
    }
    printf(" =%d\n\n", sum);
    return 0;
}

Output:

Enter the number till which you wanted the series:10

0^2 + 1^2 + 2^2 + 3^2 + 4^2 + 5^2 + 6^2 + 7^2 + 8^2 + 9^2 + 10^2 =385
