写一个贪吃蛇c语言程序

以下是一个简单的贪吃蛇C语言程序：

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

#define WIDTH 60
#define HEIGHT 20

int x, y;
int foodX, foodY;
int length = 2;
int snakeX[100], snakeY[100];
int gameOver = 0;
int score = 0;

void setup(){
    x = WIDTH / 2;
    y = HEIGHT / 2;
    srand(time(NULL));
    foodX = rand() % (WIDTH - 2) + 1;
    foodY = rand() % (HEIGHT - 2) + 1;
}

void draw(){
    system("cls");
    for(int i = 0; i < WIDTH; i++){
        printf("#");
    }
    printf("\n");

    for(int i = 1; i < HEIGHT - 1; i++){
        for(int j = 0; j < WIDTH; j++){
            if(j == 0 || j == WIDTH - 1){
                printf("#");
            } else if(i == foodY && j == foodX){
                printf("O");
            } else if(i == y && j == x){
                printf("X");
            } else {
                int print = 0;
                for(int k = 0; k < length; k++){
                    if(snakeX[k] == j && snakeY[k] == i){
                        printf("x");
                        print = 1;
                    }
                }
                if(!print){
                    printf(" ");
                }
            }
        }
        printf("\n");
    }

    for(int i = 0; i < WIDTH; i++){
        printf("#");
    }
    printf("\n");
    printf("Score: %d\n", score);
}

void input(){
    if(kbhit()){
        switch(getch()){
            case 'a':
                x--;
                break;
            case 'd':
                x++;
                break;
            case 'w':
                y--;
                break;
            case 's':
                y++;
                break;
            case 'x':
                gameOver = 1;
                break;
        }
    }
}

void logic(){
    int prevX = snakeX[0];
    int prevY = snakeY[0];
    int prev2X, prev2Y;
    snakeX[0] = x;
    snakeY[0] = y;
    for(int i = 1; i < length; i++){
        prev2X = snakeX[i];
        prev2Y = snakeY[i];
        snakeX[i] = prevX;
        snakeY[i] = prevY;
        prevX = prev2X;
        prevY = prev2Y;
    }
    if(x == foodX && y == foodY){
        length++;
        score += 10;
        foodX = rand() % (WIDTH - 2) + 1;
        foodY = rand() % (HEIGHT - 2) + 1;
    }
    if(x < 1 || x > WIDTH - 2 || y < 1 || y > HEIGHT - 2){
        gameOver = 1;
    }
    for(int i = 0; i < length; i++){
        if(snakeX[i] == x && snakeY[i] == y){
            gameOver = 1;
        }
    }
}

int main(){
    setup();
    while(!gameOver){
        draw();
        input();
        logic();
        Sleep(100);
    }
    printf("Game over!\n");
    printf("Your score is: %d\n", score);
    return 0;
}

这个程序使用了简单的ASCII字符图形来显示场景，并在控制台中运行。玩家使用方向键来控制贪吃蛇，吃掉食物并增加分数，当贪吃蛇撞到墙壁或自身时游戏结束。
