又是挥肠简单的一道题辣👀️

直接上代码👍

#include <bits/stdc++.h>
using namespace std;
int z , r , d;
int main()
{
    int n , x;
    cin >> n;
    for (int i = 0; i < n; i++) 
    {
        cin >> x;
        if (x < 90) r++;
        else if (x == 90) z++;
        else d++;
    }
    cout << z << " " << r << " " << d;
    return 0;
}

已AC，放心食用吧

#include <bits/stdc++.h>
using namespace std;
int n, m, sumzhi, sumrui, sumdun;
int main()
{
    cin >> n;
    for (int i = 1; i <= n; i++)
    {
        cin >> m;
        if (m == 90)
        {
            sumzhi += 1;
        }
        else if (m < 90)
        {
            sumrui += 1;
        }
        else 
        {
            sumdun += 1;
        }
    }
    cout << sumzhi << " " << sumrui << " " << sumdun;
    return 0;
}
