这个问题在这里已有答案:

Capture characters from standard input without waiting for enter to be pressed 15 answers

从标准输入中捕获字符,无需等待输入按下15个答案

And I know there's std::cin, but that requires the user to enter a string, then press ENTER. Is there a way to simply get the next key that is pushed without needing to press ENTER to confirm

我知道有std :: cin,但这需要用户输入一个字符串,然后按ENTER键。有没有办法简单地获得推送的下一个键,而无需按ENTER确认

You can use

您可以使用

#include <conio.h>

and then catch char with cases such as this

然后用这样的案例捕获char

char c;
if (_kbhit())
{
  c = getch();
  switch(c)
  {
  case ‘\0H’ :
  cout << "up arrow key!" << endl;
  break;
  }
}

Beware: I have not tried it... and remember to put the whole thing into a "while(true)" to test.

要注意:我没有尝试过......并且记得把整个事情放到“while(true)”进行测试。

What you're looking for is related to manipulating the console, and is OS-dependent. If you're in a UNIX-based OS, check out the curses library, and in Windows, there are getch() and kbhit() functions from <conio.h>.

您正在寻找的是与操纵控制台有关,并且与操作系统有关。如果您使用的是基于UNIX的操作系统,请查看curses库,在Windows中,可以使用中的getch()和kbhit()函数。

It looks like the most upvoted answer is a bit outdated.

看起来最受欢迎的答案有点过时了。

The ncurses library (based on the mentioned curses library) is a portable implementation available for unix and linux based operating systems, windows and others.

ncurses库(基于提到的curses库)是一个可移植的实现,可用于基于unix和linux的操作系统,窗口和其他。

It supports a wide variety of terminal interfaces.
