好吧，很闲的发一个题解（求赞） #include<bits/stdc++.h> using namespace std; int a,b[5]={0,10,20,40,50}; char x=65; int main() { cin>>a; for(int i=1;i<=5;i++) if(a>=b[i]) x++; cout<<x; return 0; } #希望不会被删掉暴徒随意

#include <iostream>

int main()
{
    using namespace std;

    long long n;
    cin >> n;
    n < 10 ? cout << "A" : n < 20 ? cout << "B" : n < 40 ? cout << "C" : n < 50 ? cout << "D" : cout << "E";
    
    return 0;
}

上来就是一个三目运算符（为什么写这么长不换行？用的VS2022写核OJ提交，这个长度在VS2022里才2/3

嘻嘻，简洁的代码来喽！！

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n;
    cin >> n;
    if(n < 10) cout << "A" << endl;
    else if(n >= 10 && n < 20) cout << "B" << endl;
    else if(n >= 20 && n < 40) cout << "C" << endl;
    else if(n >= 40 && n < 50) cout << "D" << endl;
    else cout << "E" << endl;
    return 0;
}

最后一个判断我省略了，有兴趣的可以自己加一下

这个就是代码复杂了点

if (n < 10)
    {
        cout << "A";
    }
    if (n >= 10 and n < 20)
    {
        cout << "B";
    }
    if (n >= 20 and n < 40)
    {
        cout << "C";
    }
    if (n >= 40 and n < 50)
    {
        cout << "D";
    }
    if (n >= 50 and n < 80)
    {
        cout << "E";
    }

hetao2270732 LV 7 @ 2022-8-21 18:05:05

核心代码：if..else语句

if(n<10)
      cout<<"A";
    if(n>=10&&n<20)
      cout<<"B";
    if(n>=20&&n<40)
      cout<<"C";
    if(n>=40&&n<50)
      cout<<"D";
    if(n>=50)
      cout<<"E";

完整代码

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n;
    cin>>n;
    if(n<10)
      cout<<"A";
    if(n>=10&&n<20)
      cout<<"B";
    if(n>=20&&n<40)
      cout<<"C";
    if(n>=40&&n<50)
      cout<<"D";
    if(n>=50)
      cout<<"E";
    return 0;
}

对于初学者来说，除了代码多了一点，其实很简单。

#include <iostream>
using namespace std;
int main()
{
    int n;
    cin>>n;
    if (n<10)
    {
        cout<<"A";
    }
    if (n>=10 and n<20)
    {
        cout<<"B";
    }
    if (n>=20 and n<40)
    {
        cout<<"C";
    }
    if (n>=40 and n<50)
    {
        cout<<"D";
    }
    if (n>=50 and n<80)
    {
        cout<<"E";
    }
    return 0;
}
very  滴 good！

这题也没什么难点，只用多一点的else if即可

```
#include <bits/stdc++.h>
using namespace std;
int main()
{
    int a;
    cin >> a;
    if (a < 10) cout << "A";
    else if (a >= 10 && a < 20) cout << "B";
    else if (a >= 20 && a < 40) cout << "C";
    else if (a >= 40 && a < 50) cout << "D";
    else cout << "E";
    return 0;
}
```
