啥呀，哪这么做，送你个程序
```cpp
#include<iostream>
using namespace std;
int main()
{
int a,b,c,d;
int ans,e,f;
cin>>a>>b>>c>>d;
a *= 60;
c *= 60;
ans = (c+d) - (a+b);
cout<<ans/60<<" "<<ans % 60;
}
```

送你个满分程序呀嘻嘻
```cpp
#include<iostream>
using namespace std;
int main()
{
int a,b,c,d,e,f,t,k,n;
cin>>a>>b>>c>>d;
t=a*60+b;
k=c*60+d;
n=k-t;
int x,y;
x=n/60;
y=n%60;
e=x;
f=y;
cout<<e<<" "<<f;
system("pause");
return 0;
}
```
