Question

好吧，我已经知道有些人会生气我会问这个问题因为已经有很多了，但我似乎对此有任何意义;如何在C / C ++中获得即时输入（在单个字符上）？我慢慢走向一所古老的学校“塞尔达的传说”，就像游戏一样，到目前为止这个运动似乎很好，但是即时输入会让它变得更好。

我也确定我对char和他们旁边的数字做错了，如果有人可以帮助我，或提供教程或链接，我将非常感激。

同样在研究'goto'功能时，我释放了许多人说这是混乱和混乱。是的，它有点耗费时间，但至少对我来说并不凌乱或混乱。任何人都能解释对它的所有仇恨吗？

无论如何，对不起笨拙地说，这是我到目前为止的代码，如果我犯了很多新手的错误，请随意扯掉我。

Answer 1

首先，你会为玩家可以做的每个动作制作一个条件吗？

然后，如果你想在标准输入上只有一个字符，你可以使用 Getchar 这个在c或c ++中相同的函数。

我要在这个网站上介绍你：Getchar或Getchar

如果您想避免按“Enter”，您可以进入RAW模式

system ("/bin/stty raw");

==＆GT;这将直接在stdin中发送所有char

[C]示例：

#include <stdio.h>

int main ()
{
  int c;
  puts ("Enter text. Include a dot ('.') in a sentence to exit:");
  system ("/bin/stty raw");
  do {
    c=getchar();
    putchar (c);
  } while (c != '.');

  system ("/bin/stty cooked");
  return 0;
}

C / C ++即时输入
