@[AC_710GD](/user/1017368) 你其他的没开啊。试试加上`1ll`

@[AC_710GD](/user/1017368) 你要知道,你只有`sum`开`long long`了,也就是说你把结果都算完了才开的`long long`所以没有用呀.

```cpp
#include<bits/stdc++.h>
using namespace std;
int main() {
long long sum, a1, b1, c1, a2, b2, c2, n;
scanf("%lld:%lld:%lld\n%lld:%lld:%lld\n%lld", &a1, &b1, &c1, &a2, &b2, &c2, &n);
sum = ((a2 * 3600 + b2 * 60 + c2) - (a1 * 3600 + b1 * 60 + c1)) * n;
printf("%lld", sum);
return 0;
}
```
