用c语言写一个吃豆人游戏

好的，下面是一个简单的用 C 语言实现的吃豆人游戏：

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <windows.h>

#define DX 1
#define DY 1
#define BOARD_WIDTH 20
#define BOARD_HEIGHT 20
#define MAX_DOTS (BOARD_WIDTH-2)*(BOARD_HEIGHT-2)

int x, y;
int dots;
int exit_game;
int board[BOARD_WIDTH][BOARD_HEIGHT];
int dx[4] = { 1, 0, -1, 0 };
int dy[4] = { 0, 1, 0, -1 };

void init_board();
void init_game();
void print_board();
void move(int direction);
void update();
void game_over();
void set_cursor_visible(int visible);

}

这个游戏使用了 Windows.h 头文件中的一些函数，因此只能在 Windows 操作系统上运行。在游戏中，玩家需要控制吃豆人在迷宫中移动，并尽可能地吃掉所有的豆子，避免撞到墙壁或敌人。玩家可以通过按下 W、A、S、D 键来控制吃豆人的方向，按下 Q 键可以退出游戏。
