Write a C program to calculate the sum of squares of numbers from 1 to N?

Answer 1

#include <iostream>

using namespace std;

int main()

{

int i,sum; // variables

sum = 0; // initialize sum

/* recursive addition of squares */

for (i = 1; i <= 30; i++)

sum = sum + (i * i);

cout << sum <<" is the sum of the first 30 squares."

<< endl;

return 0;

}

Answer 2

Use the following function in your program to calculate the sum of squares from 1 to max:

unsigned int sum_squares( unsigned int max )

{

unsigned int total=0, num=0;

while(num++<max)

total+=(num*num);

return(total);

}
