c语言贪吃蛇最简单代码50行

C语言贪吃蛇最简单的代码可以在50行以内实现。以下是一个简单的示例：

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

#define WIDTH 20
#define HEIGHT 20

int score = 0;

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

struct point {
    int x;
    int y;
};

struct point head, fruit;
enum direction dir;
bool gameOver;

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 == head.y && j == head.x)
                printf("O");
            else if (i == fruit.y && j == fruit.x)
                printf("@");
            else
                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 'w':
                dir = UP;
                break;
            case 's':
                dir = DOWN;
                break;
            case 'a':
                dir = LEFT;
                break;
            case 'd':
                dir = RIGHT;
                break;
            case 'x':
                gameOver = true;
                break;
        }
    }
}

void Logic() {
    struct point prev = head;

    switch (dir) {
        case UP:
            head.y--;
            break;
        case DOWN:
            head.y++;
            break;
        case LEFT:
            head.x--;
            break;
        case RIGHT:
            head.x++;
            break;
    }

    if (head.x == fruit.x && head.y == fruit.y) {
        score++;
        fruit.x = rand() % WIDTH;
        fruit.y = rand() % HEIGHT;
    }

    if (head.x < 0 || head.y < 0 || head.x >= WIDTH || head.y >= HEIGHT)
        gameOver = true;

    // Add additional collision detection logic here if needed
    
}

int main() {
    head.x = WIDTH / 2;
    head.y = HEIGHT / 2;

    fruit.x = rand() % WIDTH;
    fruit.y = rand() % HEIGHT;

    gameOver = false;
    dir = STOP;

    while (!gameOver) {
        Draw();
        Input();
        Logic();
        Sleep(10);
    }

    return 0;
}

以上代码使用了Windows.h头文件中的Sleep函数来控制游戏的速度。在绘制方面使用了简单的ASCII字符来表示蛇和食物，同时使用了conio.h头文件中的_kbhit函数和_getch函数来读取用户输入。通过不断更新蛇的位置，检测碰撞和得分，以及控制游戏的运行，实现了一个简单的贪吃蛇游戏。此代码仅为示例代码，可能还需要根据实际需求进行进一步修改和完善。
