C# .net6.0 99乘法表

先看一下效果：

再上代码

Console.WriteLine("99乘法表");
excel99();

 static void excel99()
{
    for (int a = 1; a <= 9; a++)
    {
        for (int b = 1; b <= a; b++)
        {
            Console.Write("{0} * {1} = {2}  ", b, a, a * b);
        }
        Console.WriteLine("\r\n");//每一次内层循环结束换行
    }
}
