@[Z66M99Y](/user/479204) 这样就行了，你写反了
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b,c,d,e,f;
cin>>a>>b>>c>>d;
e=c-a;
if(b>d)
{
f=(60+d)-b;
e--;
}
else
f=d-b;
cout<<e<<" "<<f<<endl;
return 0;
}
```
~~怎么还有人会把代码写反的啊啊啊啊啊啊啊啊~~

```
#include<iostream>
using namespace std;
int main()
{
int a,b,c,d,m1,m2,h,hour,min;
cin>>a>>b>>c>>d;
m1=60*a+b;
m2=60*c+d;
h=m2-m1;
hour=h/60;
min=h%60;
cout<<hour<<" "<<min<<endl;
return 0;
}
```
## 这程序虽然变量多了点，但个人觉得挺好理解的
