tem是浮点类型的，怎能自增呢？
```cpp
#include <bits/stdc++.h>
using namespace std;
int main() {
int HH = 7, MM = 50, tem;
double s, v;
cin >> s >> v;
tem= s / v;
if (tem < s / v) {
tem++;
}
MM -= tem;
while (MM < 0) {
HH--;
MM += 60;
if (HH < 0) {
HH = 23;
}
}
cout << setw(2) << setfill('0') << HH << ':' << setw(2) << setfill('0') << MM;
return 0;
}
```

浮点类型能自增
例如：1.34+1=2.34 **** 2.6+1=3.6

```cpp
if (tem < s / v) { #若tem=3.14
tem++; #则tem=4.14
}
```
