c语言贪吃蛇游戏代码mac

以下是一个简单的 C 语言贪吃蛇游戏代码，适用于 macOS 系统：

#include <stdio.h>
#include <stdlib.h>
#include <termios.h>
#include <unistd.h>
#include <fcntl.h>
#include <time.h>

#define UP 'w'
#define DOWN 's'
#define LEFT 'a'
#define RIGHT 'd'

}

该代码使用了标准库中的头文件 `<stdio.h>`、`<stdlib.h>`、`<termios.h>`、`<unistd.h>`、`<fcntl.h>` 和 `<time.h>`。

注意：由于 macOS 系统没有 kbhit 函数，所以该代码使用了 termios.h 头文件中的 tcsetattr 和 tcgetattr 函数来实现键盘输入的非阻塞。
