乘法口诀表

#include <iostream>
using namespace std;
int main()
{
    for (int i = 1;i <= 9;i++)
    {
        for (int j = 1;j <= i;j++)
        {
            cout << j << "*" << i << "=" << i * j << "\t";
        }
        cout << endl;
    }
    system("pause");
    return 0;
}

这个没看就出来了......不难......
