C ++在Windows中改变规范模式 [英] C++ change canonical mode in windows

问题描述

找到一堆线程后，我没有找到任何在Windows上，只有Linux，Ubuntu等。

After finding a bunch of threads on this I did not find any on Windows, only Linux, Ubuntu etc.

总之，我想知道的是如何关闭规范模式，以便在控制台中的输入导致即时输入，而不必按Enter键。

In short what I am trying to find out is how to turn canonical mode off so that input in the console results in instant input without having to press enter.

较长版本。这是我现在想做的：
当PGM暂停（基于文本的游戏）时，用户被要求输入箭头键来移动2D阵列上的播放器。但是 cin.get（）， cin.ignore（）

Longer version. This is what I am trying to do right now: When the PGM is pausing (text based game) the user is asked to enter an arrow key to move the player around on the 2D array. But cin.get(), cin.ignore() and some other things I've tried all require pressing enter before it will continue.

臭名昭着的系统（pause> nul）; em>实际工作，但因为我在各种其他地方阅读是非常糟糕的做法。

The infamous system("pause>nul"); does actually work, but as I've read in various other places is very bad practice.

这是代码的一部分。 cout 语句仅用于测试目的：

This is part of the code. the cout statements are only for testing purpose:

//While loop
if(GetAsyncKeyState(VK_UP)){
        cout << "up" << endl;
}
else if(GetAsyncKeyState(VK_DOWN)){
        cout << "down" << endl;
}
else if(GetAsyncKeyState(VK_LEFT)){
        cout << "left" << endl;
}
else if(GetAsyncKeyState(VK_RIGHT)){
        cout << "right" << endl;
}
else{
    break;}

//pauze and check for arrow key input here

推荐答案

也可以在Windows上使用 getch ：

You can use getch also on windows:

我知道它是C，你得到了废弃的警告，但它工作...

I know it is C, and you got the deprecated warning, but it works...

循环，直到您按Enter：

this code run in a loop till you press Enter:

检查当您按箭头键时发生什么...

check what happen when you press an arrow key...

#include <stdio.h>
#include<conio.h>
int main ()
{
  int c;
  do {
    c=getch();
    printf("%d\n",c);
  } while (c != 13);
  return 0;
}
