Fundamentals of Computer Programming - Old Questions

4. Write a program that uses a “for” loop to compute and prints the sum of a given numbers of squares.

#include<stdio.h>
int main()
{
  int i, n, sum=0;

  printf("Enter n value: ");
  scanf("%d", &n);

  for(i=0; i<=n; i++)
  {
     sum += (i*i);
  }

  printf("Sum of squares of first %d natural numbers = %d", n, sum);
  return 0;
}
