没那么麻烦吧,这又是重定向又是struct的
看看这个:
```cpp
#include<iostream>
using namespace std;
int main() {
int a, b, c;
char s;
cin >> a >>s>> b >>s>> c;
int q, w, e;
cin >> q >> s >> w >> s >> e;
int n;
cin >> n;
long long l1 = a * 3600 + b * 60 + c;
long long l2 = q * 3600 + w * 60 + e;
long long l3 = l2 - l1;
if (l3 < 0) {
l3 = 0;
}
cout << l3 * n;
}
```

Look at me
```
#include<bits/stdc++.h>
using namespace std;
#define H 3600
#define M 60
#define S 1
int main(){
long long int H1,H2,M1,M2,S1,S2,n,tmp;char ch;
cin>>H1>>ch>>M1>>ch>>S1>>H2>>ch>>M2>>ch>>S2>>n;
tmp = (((H2-H1)*H)*n)+(((M2-M1)*M)*n)+(((S2-S1)*S)*n);
cout<<tmp;
return 0;
}
```
