Re: [問題] 九九乘法表
我照你的格式改成 for 迴圈...
string str;
Console.Write(" ");
for(int x=1;x<10;x++)
{
str = Convert.ToString(x);
Console.Write(str.PadLeft(3));
}
Console.Write("\n");
for(int y=1;y<10;y++)
{
Console.Write(y);
for(int x=1;x<10;x++)
{
str = Convert.ToString(x * y);
Console.Write(str.PadLeft(3));
}
Console.Write("\n");
}

ssccg大大高招 ^_^ 程式又簡化了...為什麼可以這樣用啊？
我已經安裝 VS 2010 Express 已經可以檢驗您的說法，效果是一樣的，正確無誤。XD
這樣省掉一個字串變數的宣告...真的很精簡...^_^
Console.Write(" ");
for (int x = 1; x < 10; x++)
{
Console.Write("{0,3}", x);
}
Console.WriteLine();
for (int y = 1; y < 10; y++)
{
Console.Write(y);
for (int x = 1; x < 10; x++)
{
Console.Write("{0,3}", x * y);
}
Console.WriteLine();
}
Console.ReadLine();

不加參數就可以直接印出來 Console.Write("{0,3}") 如果後面要印出 x*y
就要寫兩行，當然...這不是本問題的求解...可能在別的問題上吧 XD
Console.Write("{0,3}");
Console.Write(x * y);
