Question

求c#语言程序设计九九乘法表控制台程序

Answer 1

using System;

class ForApp
{
public static void Main()
{
//打印表头
Console.WriteLine("九九乘法表");

//打印九九表
for(int i = 1; i <= 9; i++)
{
//计算并格式化输出九九表的内容
for(int j = 1; j <= i; j++)
{
Console.Write("{0}x{1}={2}\t", i, j, i*j);
}

//换行
Console.WriteLine();
}
}
}

Answer 2

for(int i=1;i<=9;i++){
for(int j=1;j<=i;j++){
Console.Write(i*j);
Console.Write(" ");
if(i==j){
Console.Write("\n");
}
}
}

Answer 3

for (int i = 1; i <= 9; i++)
{
for (int j = i; j <= 9; j++)
{
if (i * j > 9)
Console.Write("{0} * {1} = {2} ", i, j, i * j);
else
Console.Write("{0} * {1} = {2} ", i, j, i * j);
}
Console.WriteLine();
for (int k = 0; k < i; k++)
{
Console.Write(" ");
}
}
Console.ReadKey();

Answer 4

static void Main(string[] args)
{
for (int i = 1; i <= 9; i++)
{
for (int j = i; j <= 9; j++)
{
if (i * j > 9)
Console.Write("{0} * {1} = {2} ", i, j, i * j);
else
Console.Write("{0} * {1} = {2} ", i, j, i * j);
}
Console.WriteLine();
for (int k = 0; k < i; k++)
{
Console.Write(" ");
}
}
Console.ReadKey();
}
