求各位帮帮忙 刚开始学！

我也是刚开始学的，我只能用我会的方法改了一下你的代码
#include <iostream>
#include<iomanip>
using namespace std;
int main()
{
int n;
cout << "Enter a positive interger:";
cin >> n;
int a,b;
cout << "The interger you had enter is:" << n << endl;
for(int loop = 8;loop > 0;loop--)
{
if (n != 0 && n % 2 == 0)
{
a = n / 2;
cout <<"The orbit of "<< n << " is " << a << endl;
n = a;
}
else
{
b = 3 * n + 1;
cout << "The orbit of " << n << " is " << b << endl;
n = b;
}
}
system("pause");
}

应该是这种结果吧

要学这个的话，都是自学嘛还是去培训机构？

楼主自学的么

楼主以前有木有学过Java或者c语言什么的
