不是，这代码给我AC了！！！

#include <bits/stdc++.h>
using namespace std;
int main()
{
    int n, m, a;
    cin >> n >> m >> a;
    int top1 = 1, top2 = 1;
    while (a--)
    {
        cout << top1 << " " << top2 << endl;
        if (top1 == n)
            top1 = 0;
        if (top2 == m)
            top2 = 0;
        top1++;
        top2++;
    }
    return 0;
}
