用c语言编写贪吃蛇代码是多少

以下是用C语言编写贪吃蛇游戏的基本代码，仅供参考：

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

#define WIDTH 30
#define HEIGHT 20

int map[HEIGHT][WIDTH];

typedef struct Snake
{
    int x;
    int y;
    struct Snake *next;
} Snake;

typedef struct Food
{
    int x;
    int y;
} Food;

Snake *head, *tail;
Food food;

int dir = 1;
int score = 0;

void init()
{
    int i, j;
    for (i = 0; i < HEIGHT; i++)
        for (j = 0; j < WIDTH; j++)
            map[i][j] = 0;
    head = (Snake*)malloc(sizeof(Snake));
    tail = (Snake*)malloc(sizeof(Snake));
    head->x = WIDTH / 2;
    head->y = HEIGHT / 2;
    head->next = tail;
    tail->x = head->x - 1;
    tail->y = head->y;
    tail->next = NULL;
    map[head->y][head->x] = 1;
    map[tail->y][tail->x] = 1;
    food.x = rand() % WIDTH;
    food.y = rand() % HEIGHT;
}

void draw()
{
    int i, j;
    system("cls");
    printf("Score: %d\n\n", score);
    for (i = 0; i < HEIGHT; i++)
    {
        for (j = 0; j < WIDTH; j++)
        {
            if (map[i][j] == 0)
                printf(".");
            else if (map[i][j] == 1)
                printf("*");
            else if (map[i][j] == 2)
                printf("#");
            else if (map[i][j] == 3)
                printf("O");
        }
        printf("\n");
    }
}

void update()
{
    int i, j;
    Snake *p = (Snake*)malloc(sizeof(Snake));
    p->x = head->x;
    p->y = head->y;
    p->next = head->next;
    head->next = p;
    head->x += dir % 2 * (2 - dir);
    head->y += (dir + 1) % 2 * (dir - 1);
    if (head->x < 0 || head->x >= WIDTH || head->y < 0 || head->y >= HEIGHT || map[head->y][head->x] == 1)
        exit(0);
    if (head->x == food.x && head->y == food.y)
    {
        score++;
        food.x = rand() % WIDTH;
        food.y = rand() % HEIGHT;
    }
    else
    {
        map[tail->y][tail->x] = 0;
        tail = tail->next;
        free(tail->next);
        tail->next = NULL;
    }
    p = head;
    while (p != NULL)
    {
        map[p->y][p->x] = 1;
        p = p->next;
    }
    map[food.y][food.x] = 2;
    map[head->y][head->x] = 3;
}

void control()
{
    if (_kbhit())
    {
        switch (_getch())
        {
        case 'w':
            dir = 0;
            break;
        case 'a':
            dir = 3;
            break;
        case 's':
            dir = 2;
            break;
        case 'd':
            dir = 1;
            break;
        }
    }
}

int main()
{
    init();
    while (1)
    {
        draw();
        update();
        control();
        Sleep(100);
    }
    return 0;
}

这只是一个简单的贪吃蛇游戏，你可以根据自己的需要进行修改和扩展。
