@DadCelL

printf("%d")

改成

printf("%lld")

@DadCelL 应为：

#include<iostream>
using namespace std;
int main()
{
    int a,s=0;
    cin>>a;
    while(a!=1)
    {
        if(a%2==1)
        {
            cout<<a<<" ";
            a=a*3+1;
            s++;
        } 
        if(a%2==0)
        { 
            a=a/2;
        }
        if(a==1) break;
    }
    if(s==0)
    {
        cout<<"No number can be output!";
    }
    return 0;
}

我用的是cin，cout
