为什么提交通过，调试没结果

#include <iostream>
#include <algorithm>
using namespace std;

int main()
{
    int max = 0,max_index = 0,x;

    for( int i = 1; i <= 100; i++)
    {
        cin >> x;
        if(x > max) max = x,max_index = i;
    }
    cout << max << endl;
    cout << max_index <<endl;

    return 0;
}
