Question

如何用DO-WHILE输出九九乘法表(在C#中)

Answer 1

2个循环 i,j 变量, i++父循环
子循环j++,当j<=i时做输出 i.tostring() + "×" + j.tostring() +"=" + (i*j).tostring()，否则就break,到父循环闲扯一句,
用javascript做, 很好玩咧,
因为可以 
var title=i + "*" + j;
document.write(title + "="+ eval(title));
哈哈

Answer 2

using System;
using System.Collections.Generic;
using System.Text;namespace 九九乘法表
{
    class Program
    {
        static void Main(string[] args)
        {
            int i,i1,j1, j, sum;
            i = 1;
            j = 1;
            sum = 1;
            do
            {
                i1 = i; j1 = j;//i1，j1 用控制每行数字的变化
              
                    do
                    {
                        sum = i1 * j1;
                        Console.Write("{0}*{1}={2}   ",i1,j1, sum);
                        j1--;
                        i1++;
                        if (j1 < 1)
                        {
                            Console.WriteLine();
                        }
                    } while (j1>=1）//控制行的输出
                               j++;            } while (j < 10);//控制总的循环次数
        }
    }
}

Answer 3

抱歉哈，上面程序错了
这是新的
using System;
using System.Collections.Generic;
using System.Text;namespace 九九乘法表
{
    class Program
    {
        static void Main(string[] args)
        {            int  i=1, j=1,sum =1;
            do
            {
                sum = i * j;
                Console.Write("{0}*{1}={2}   ", i, j, sum);
                i++;
                if (i > j)
                {
                    Console.WriteLine();
                    j++;
                    i = 1;
                }            } while (j <= 9);
                   }
    }
