贪吃蛇c语言程序代码

下面是一个简单的贪吃蛇C语言程序代码：

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

#define WIDTH 50
#define HEIGHT 20

int x, y, fruit_x, fruit_y, score;
int tail_x[100], tail_y[100], tail_len = 0;
char map[HEIGHT][WIDTH];

void init_map() {
    for (int i = 0; i < HEIGHT; i++) {
        for (int j = 0; j < WIDTH; j++)
            map[i][j] = ' ';
    }
    for (int i = 0; i < tail_len; i++)
        map[tail_y[i]][tail_x[i]] = 'o';
    map[y][x] = 'O';
    map[fruit_y][fruit_x] = 'X';
}

void draw_map() {
    system("cls");
    printf("Score: %d\n", score);
    for (int i = 0; i <= WIDTH + 1; i++)
        printf("-");
    printf("\n");
    for (int i = 0; i < HEIGHT; i++) {
        printf("|");
        for (int j = 0; j < WIDTH; j++)
            printf("%c", map[i][j]);
        printf("|\n");
    }
    for (int i = 0; i <= WIDTH + 1; i++)
        printf("-");
    printf("\n");
}

void move_snake() {
    int prev_x = x, prev_y = y;
    if (_kbhit()) {
        switch (_getch()) {
            case 'w':
                y--;
                break;
            case 's':
                y++;
                break;
            case 'a':
                x--;
                break;
            case 'd':
                x++;
                break;
        }
    }
    if (x == fruit_x && y == fruit_y) {
        tail_len++;
        score++;
        fruit_x = rand() % WIDTH;
        fruit_y = rand() % HEIGHT;
    }
    for (int i = 0; i < tail_len; i++) {
        int tmp_x = tail_x[i], tmp_y = tail_y[i];
        tail_x[i] = prev_x;
        tail_y[i] = prev_y;
        prev_x = tmp_x;
        prev_y = tmp_y;
    }
    for (int i = 0; i < tail_len; i++) {
        if (x == tail_x[i] && y == tail_y[i])
            exit(1);
    }
    if (x < 0 || x >= WIDTH || y < 0 || y >= HEIGHT)
        exit(1);
}

int main() {
    srand(time(NULL));
    x = WIDTH / 2;
    y = HEIGHT / 2;
    fruit_x = rand() % WIDTH;
    fruit_y = rand() % HEIGHT;
    while (1) {
        init_map();
        draw_map();
        move_snake();
    }
    return 0;
}

这个程序使用了Windows系统下的conio.h库来实现键盘输入的检测，因此只能在Windows系统下运行。如果需要在其他系统上运行，需要使用其他方式来检测键盘输入。
