我用了防除以0的方法做的还是这样

#include <bits/stdc++.h>
using namespace std;
int main ()
{
    int n, k, suma = 0, sumb = 0;
    double resa = 0;
    cin >> n >> k;
    for (int i = 1; i <= n; i++)
    {
        if (i % k == 0)suma += i, resa ++;
        else sumb += i;
    }
    if (resa == n)cout << fixed << setprecision (1) << suma / resa << " " << 0.0;
    else if (resa == 0)cout << fixed << setprecision (1) << 0.0 << " " << sumb / (n - resa);
    else cout << fixed << setprecision (1) << suma / resa << " " << sumb / (n - resa);
    return 0;
}

我刚交了一发，过了。是不是数据被修正了？
