C ++控制台键盘事件

如果要按下某个键，我希望Windows控制台程序执行某些操作，像

I want a Windows console program to do something if a certain key is pressed down, something like

while(1)
{
    ....
    if(the key 'o' is pressed down)
      ....
}

但我不知道要在 if 语句中添加什么.如何检查键"o"是否按下?

but I don't know what to put in the if statement. How do I check if the key 'o' is pressed down?

我正在使用Windows 7 64位和Visual Studio Professional 2008.

推荐答案

您应该在应用程序中注册按键事件(假设这是Windows GUI应用程序)，而不是忙于查询按键，并检查按键您感兴趣.

Rather than busy-polling for a keypress, you should register for key events in your application (assuming this is a Windows GUI app), and check for the keys you're interested in.

如果您实际上是在制作控制台应用程序，请参见此处: C ++控制台键盘事件
