帮我写贪吃蛇的C语言程序

当然可以帮你写贪吃蛇的C语言程序！下面是一个简单的贪吃蛇程序的示例代码：

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

#define WIDTH 20
#define HEIGHT 20

int score;
int gameover;
int length;
int headX, headY;
int fruitX, fruitY;
int tailX[100], tailY[100];
enum eDirecton { STOP = 0, LEFT, RIGHT, UP, DOWN };
enum eDirecton dir;

void Setup()
{
    gameover = 0;
    dir = STOP;
    headX = WIDTH / 2;
    headY = 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 == headY && j == headX)
                printf("O");
            else if (i == fruitY && j == fruitX)
                printf("F");
            else
            {
                int printTail = 0;
                for (int k = 0; k < length; k++)
                {
                    if (tailX[k] == j && tailY[k] == i)
                    {
                        printf("o");
                        printTail = 1;
                    }
                }
                if (!printTail)
                    printf(" ");
            }
            if (j == WIDTH - 1)
                printf("#");
        }
        printf("\n");
    }

    for (int i = 0; i < WIDTH + 2; i++)
        printf("#");
    printf("\n");
    printf("Score: %d\n", score);
}

void Input()
{
    if (_kbhit())
    {
        switch (_getch())
        {
        case 'a':
            dir = LEFT;
            break;
        case 'd':
            dir = RIGHT;
            break;
        case 'w':
            dir = UP;
            break;
        case 's':
            dir = DOWN;
            break;
        case 'x':
            gameover = 1;
            break;
        }
    }
}

void Logic()
{
    int prevX = tailX[0];
    int prevY = tailY[0];
    int prev2X, prev2Y;
    tailX[0] = headX;
    tailY[0] = headY;

    for (int i = 1; i < length; i++)
    {
        prev2X = tailX[i];
        prev2Y = tailY[i];
        tailX[i] = prevX;
        tailY[i] = prevY;
        prevX = prev2X;
        prevY = prev2Y;
    }

    switch (dir)
    {
    case LEFT:
        headX--;
        break;
    case RIGHT:
        headX++;
        break;
    case UP:
        headY--;
        break;
    case DOWN:
        headY++;
        break;
    }

    if (headX >= WIDTH)
        headX = 0;
    else if (headX < 0)
        headX = WIDTH - 1;

    if (headY >= HEIGHT)
        headY = 0;
    else if (headY < 0)
        headY = HEIGHT - 1;

    for (int i = 0; i < length; i++)
    {
        if (tailX[i] == headX && tailY[i] == headY)
            gameover = 1;
    }

    if (headX == fruitX && headY == fruitY)
    {
        score += 10;
        fruitX = rand() % WIDTH;
        fruitY = rand() % HEIGHT;
        length++;
    }
}

int main()
{
    Setup();
    while (!gameover)
    {
        Draw();
        Input();
        Logic();
        Sleep(10); // 程序暂停10毫秒
    }
    return 0;
}

这是一个基本的贪吃蛇游戏程序，使用了 `conio.h` 和 `windows.h` 头文件来实现一些控制台窗口的功能。你可以将上述代码保存为一个 C 文件，然后编译运行即可尝试玩贪吃蛇游戏。希望这个示例代码能帮到你！如果有任何问题，请随时向我提问。
