a/b没强制转换成double
by a1111a @ 2023-12-30 10:29:26
```cpp
#include<iostream>
#include<cmath>
using namespace std;
int main(){
int a,b;
int c;
double d,e;
cin>>a>>b;
c=int((double)a/b+0.999999999)+10;
d=int((8-ceil(c/60.0)));
if(d<0) d+=24;
e=60-(c+1)%60;
if(d<10){
if(e<10) cout<<"0"<<d<<":"<<"0"<<e;
else cout<<"0"<<d<<":"<<e;
}
else{
if(e<10) cout<<d<<":"<<"0"<<e;
else cout<<d<<":"<<e;
}
}
```

```cpp
#include<iostream>
#include<cmath>
using namespace std;
int main(){
int a,b;
int c;
double d,e;
cin>>a>>b;
c=int((double)a/b+0.999999999)+10;
d=int((8-ceil(c/60.0)));
if(d<0) d+=24;
e=60-c%60;
if(d<10){
if(e<10) cout<<"0"<<d<<":"<<"0"<<e;
else cout<<"0"<<d<<":"<<e;
}
else{
if(e<10) cout<<d<<":"<<"0"<<e;
else cout<<d<<":"<<e;
}
}
```
还有这个，e=60-c%60;不是e=60-(c+1)%60
