看了一些题解好像都是化成分钟再求解，做题的时候也想到了但是不想这样做，提供一种直接分钟和小时分开算的思路，简单的判断语句。

#include <iostream>

using namespace std;
int main()
{
    int a, b, c, d;
    int hour, minute;

    cin >> a >> b >> c >> d;

    //分
    if (d - b >= 0)
    {
        minute = d - b;
        //时 
        if (c - a > 0) hour = c - a;
        else if (c == a) 
        {
            if (minute > 0) hour = 0;
            else hour = 24;
        }
        else hour = c - a + 24;
    }
    else
    {
        minute = d - b + 60;
        //时 
        if (c - a > 0 ) hour = c - a - 1;
        else if (c == a) hour = 23;
        else hour = c - a + 23;
    }

    cout << "O JOGO DUROU " << hour << " HORA(S) E " << minute << " MINUTO(S)" << endl;

    return 0;
}
