用C语言编写贪吃蛇游戏

好的，我可以为你提供一个简单的贪吃蛇游戏的C语言代码。以下是代码：

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

#define MAX_X 20
#define MAX_Y 20
#define SNAKE_LENGTH 50

int x, y, fruitX, fruitY, score, gameOver;
int snakeX[SNAKE_LENGTH], snakeY[SNAKE_LENGTH];
int snakeLength = 3;
char direction;

void Setup()
{
    gameOver = 0;
    direction = 'w';
    x = MAX_X / 2;
    y = MAX_Y / 2;

    fruitX = rand() % MAX_X;
    fruitY = rand() % MAX_Y;

    score = 0;
}

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

    printf("Score: %d\n\n", score);

    for (int i = 0; i < MAX_X + 1; i++)
    {
        printf("#");
    }

    printf("\n");

    for (int i = 0; i < MAX_Y; i++)
    {
        for (int j = 0; j < MAX_X; j++)
        {
            if (j == 0 || j == MAX_X - 1)
            {
                printf("#");
            }
            else if (i == y && j == x)
            {
                printf("O");
            }
            else if (i == fruitY && j == fruitX)
            {
                printf("F");
            }
            else
            {
                int print = 0;

                for (int k = 0; k < snakeLength; k++)
                {
                    if (snakeX[k] == j && snakeY[k] == i)
                    {
                        printf("o");
                        print = 1;
                    }
                }

                if (!print)
                {
                    printf(" ");
                }
            }
        }

        printf("\n");
    }

    for (int i = 0; i < MAX_X + 1; i++)
    {
        printf("#");
    }

    printf("\n");
}

void Input()
{
    if (_kbhit())
    {
        switch (_getch())
        {
        case 'w':
            direction = 'w';
            break;
        case 'a':
            direction = 'a';
            break;
        case 's':
            direction = 's';
            break;
        case 'd':
            direction = 'd';
            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 < snakeLength; i++)
    {
        prev2X = snakeX[i];
        prev2Y = snakeY[i];

        snakeX[i] = prevX;
        snakeY[i] = prevY;

        prevX = prev2X;
        prevY = prev2Y;
    }

    switch (direction)
    {
    case 'w':
        y--;
        break;
    case 'a':
        x--;
        break;
    case 's':
        y++;
        break;
    case 'd':
        x++;
        break;
    }

    if (x > MAX_X - 2 || x < 1 || y > MAX_Y - 1 || y < 1)
    {
        gameOver = 1;
    }

    for (int i = 0; i < snakeLength; i++)
    {
        if (snakeX[i] == x && snakeY[i] == y)
        {
            gameOver = 1;
        }
    }

    if (x == fruitX && y == fruitY)
    {
        score += 10;

        fruitX = rand() % MAX_X;
        fruitY = rand() % MAX_Y;

        snakeLength++;
    }
}

int main()
{
    Setup();

    while (!gameOver)
    {
        Draw();
        Input();
        Logic();

        Sleep(50);
    }

    printf("Game Over!\n");
    printf("Your Score: %d\n", score);

    return 0;
}

这是一个比较简单的代码，如果你想增加游戏难度或者添加更多功能，可以在此基础上进行修改和扩展。
