应该不难吧？

#include <iostream>
using namespace std;
int main(){
    int a;
    cin >> a;
    while(a!=1){
        if(a%2==0){
            cout << a << "/2=";
            a/=2;
            cout << a << endl;
        }else{
            cout << a << "*3+1=";
            a=a*3+1;
            cout << a << endl;
        }
    }
    cout << "End";
    return 0;
}
