@Yu09217777 输出部分，你加了空格，删掉就行了

首先，你的输出里应该没有空格，你加了一个空格

cout << n << " / 2 = " << n / 2 << endl;

#include <bits/stdc++.h>
using namespace std;
bool J(int n){
    if(n % 2 == 1){
        return true;
    }
    return false;
}
int main(){
    long long n,m;
    cin>>n;
    while(n != 1){
        if( J(n) ){
            m = n;
            n = n*3+1;
            cout << m << "*3+1=" << n << endl;
        }else{
            m = n;
            n = n / 2;
            cout << m << "/2=" << n << endl;
        }
    }
    cout << "End" << endl;
    return 0;
}

本人根据你的代码调整了一下\

以后写代码一定要注意细节啊
