# Sum of squares of first n natural numbers

Here given code implementation process.

```
/*
C program for
Sum of squares of first n natural numbers
*/
#include <stdio.h>
void squaresOfNaturalNo(int n)
{
long long int sum = 0;
if (n > 0)
{
// Normal calculation
// Execute loop 1 to n and calculate squared.
for (int i = 1; i <= n; ++i)
{
// Add square
sum += (i *i);
}
}
printf("\n Sum of square in %d natural number is %lld", n, sum);
}
