Question:
Write a program to calculate the summation of following series.

\(2^2 + 4^2 + 6^2 + \dots + 100^2\)

\(2^2 + 4^2 + 6^2 + \dots + 100^2\)
Answer:

#include <stdio.h>

int main() {
    int sum = 0;

    // Loop starts at 2 and increases by 2 each time (even numbers only)
    for (int i = 2; i <= 100; i += 2) {
        sum += (i * i);
    }

    printf("%d", sum);

    return 0;
}
