如何检测用户在C ++（控制台）中是否按任何键？ [英] How can I detect if any key is pressed by the user in C++ (console)?

问题描述

我正在编写一个C ++ CLI应用程序，如何检测用户是否按下任何键。我已经看到在c＃，但如何在c ++中实现

I am writing a C++ CLI application how can I detect if any key is pressed by the user. I've seen that in c# but how can it be implement in c++

while(1)
     {
      while(/* code to check if any key is pressed*/)
           {        //rest of the code
                    // sleep function
           }
     }

提示：像在CLI游戏中移动或采取某些动作，当按下一个键或不做任何事如果没有输入。

Hint: like in CLI games to move or to take certain action when a key is pressed or don't do any thing if no input is given.

推荐答案

我们可以在c ++中使用_kbhit如果按任何键，_kbhit等于1。你必须清除_kbhit缓冲区，否则它将保持为1.清除的方法是character = getch（）;这将保存最后输入的键的字符，您可以比较，并决定要对哪个键执行哪个操作。

we can use _kbhit() function in c++. _kbhit is equal to 1 if any key is pressed. You have to clear the _kbhit buffer else it will remain 1. Method for clearing is character = getch(); This will save the last entered key in character which you can compare and decide which action to perform on which key.
