心态给弄的特别不好了 求dalao给看看

#include <iostream>
using namespace std;

int main()
{
    int beginh , beginm , endh , endm;
    int hour = 0 , min = 0;
    cin >> beginh >> beginm >> endh >> endm;
    hour = endh - beginh;
    if(beginm <= endm)
    {
        min = beginm - endm;
    }
    else
    {
        min = endm + 60 - beginm;
        hour -= 1;
    }
    if(hour == 0)
    {
        cout << min << endl;
    }
    else
    {
        cout << hour << " " << min << endl;
    }
    return 0;
}
