c语言实现贪吃蛇的代码

以下是一个简单的 C 语言实现贪吃蛇的代码：

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

#define WIDTH 40
#define HEIGHT 20

int x, y, fruitX, fruitY, score, gameover;

enum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };
enum eDirection dir;

void Setup()
{
    gameover = 0;
    dir = STOP;
    x = WIDTH / 2;
    y = HEIGHT / 2;
    fruitX = rand() % WIDTH;
    fruitY = rand() % HEIGHT;
    score = 0;
}

void Draw()
{
    system("cls");

    for (int i = 0; i < WIDTH + 2; i++)
        printf("#");
    printf("\n");

    for (int i = 0; i < HEIGHT; i++)
    {
        for (int j = 0; j < WIDTH; j++)
        {
            if (j == 0)
                printf("#");
            if (i == y && j == x)
                printf("O");
            else if (i == fruitY && j == fruitX)
                printf("F");
            else
