思路:

最简单的方法, 五重循环输出每一位.

#include <iostream>
using namespace std;

int main()
{
    ios::sync_with_stdio(false);
    cin.tie(0);

    for (int a = 0; a <= 1; a++)
        for (int b = 0; b <= 1; b++)
            for (int c = 0; c <= 1; c++)
                for (int d = 0; d <= 1; d++)
                    for (int e = 0; e <= 1; e++)
                        cout << a << b << c << d << e << endl;

    return 0;
}
