解答 - 判斷倍數

a是b的倍數，即代表 a取餘數b為0

#include<iostream>
using namespace std;

int main()
{
    int a, b;

    while( cin >> a >> b )
    {
        if( a%b == 0 )
        {
            cout << "Yes" << endl;
        }
        else
        {
            cout << "No" << endl;
        }
    }

    return 0;
}
