@zzh0118 你的判断条件太多了

by 2345A @ 2024-03-05 10:35:23

@zzh0118 再用你的可能的思路写一个：

#include<bits/stdc++.h>
using namespace std;
int main(){
    int t,n,x,y;
    double s,v;//小数，小数！！！
    cin>>s>>v;
    t=ceil(s/v)+10;
    n=8*60+24*60-t;
    if(n>=24*60) n-=24*60;
    x=n/60;
    y=n%60;
    if(x>=10){//你一般用的优良马蜂
        if(y>=10) cout<<x<<":"<<y;
        else cout<<x<<":"<<"0"<<y;
    }
    else {
        if(y>=10) cout<<"0"<<x<<":"<<y;
        else cout<<"0"<<x<<":"<<"0"<<y;
    }
    return 0;
}

@zzh0118 最后，你前面的代码没有问题，后面的代码判断的太多了，所以我修改了你的代码主要是你的马蜂我真看不懂

#include<bits/stdc++.h>
using namespace std;
int cnt=8*60+24*60,num,fen,shi;
int main(){
    double s,u;
    cin>>s>>u;
    num=ceil(s/u)+10;//ceil的意思是向上取整，因为C++默认向下取整;
    cnt=8*60+24*60-num;
    if(cnt>=24*60){
        cnt-=24*60;
    }
    shi=cnt/60;
    fen=cnt%60;
    if(shi>=10)
    {
        if(fen>=10)
        cout<<shi<<":"<<fen;
        else
        cout<<shi<<":0"<<fen;
    }
    else
    {
        if(fen>=10)
        {
            cout<<"0"<<shi<<":"<<fen;
        }
        else
        cout<<"0"<<shi<<":0"<<fen;
    }
    return 0;
}
