为什么75分？

#include<bits/stdc++.h>
using namespace std;

int main(){
    int n;
    cin>>n;
    if(n==1) cout<<"End";
    while(1){
        if(n==2){
            cout<<"2/2=1"<<endl;
            break;
        } 
        if(n%2!=0){
            cout<<n<<'*'<<'3'<<'+'<<'1'<<'='<<n*3+1<<endl;
            n=n*3+1;
        }
        else{
            cout<<n<<'/'<<'2'<<'='<<n/2<<endl;
            n=n/2;
        }
    }
    cout<<"End";
    return 0;
}

我样例过了。

@Your_Name 如果n=1的话你这个程序会输出两个End吧。

#include<bits/stdc++.h>
using namespace std;

int main(){
    int n;
    cin>>n;
    if(n==1) {cout<<"End";return 0;}//修改处。
    while(1){
        if(n==2){
            cout<<"2/2=1"<<endl;
            break;
        } 
        if(n%2!=0){
            cout<<n<<'*'<<'3'<<'+'<<'1'<<'='<<n*3+1<<endl;
            n=n*3+1;
        }
        else{
            cout<<n<<'/'<<'2'<<'='<<n/2<<endl;
            n=n/2;
        }
    }
    cout<<"End";
    return 0;
}

我没试应该可以AC。

实测已过

#include<bits/stdc++.h>
using namespace std;

int main(){
    int n;
    cin>>n;
    if(n==1) cout<<"End";
  else{
    while(1){
        if(n==2){
            cout<<"2/2=1"<<endl;
            break;
        } 
        if(n%2!=0){
            cout<<n<<'*'<<'3'<<'+'<<'1'<<'='<<n*3+1<<endl;
            n=n*3+1;
        }
        else{
            cout<<n<<'/'<<'2'<<'='<<n/2<<endl;
            n=n/2;
        }
    }
    cout<<"End";
  }
    return 0;
}

如果n!=1下面就不运行了
