C语言贪吃蛇程序代码完整

编写一个完整的C语言贪吃蛇游戏代码会比较复杂，因为涉及到图形界面、键盘输入处理、游戏循环以及蛇体动态更新等多个部分。下面是一个简化的文本模式贪吃蛇的示例，仅包含基本的游戏规则，不包括图形化：

#include <stdio.h>
#include <stdlib.h>
#define BOARD_SIZE 10
#define HEAD 0
#define APPLE 1

typedef struct {
    int x, y;
} Position;

Position snake[5] = { {0, 0}, {1, 0}, {2, 0}, {1, 1}, {1, 2} };
int apple_x, apple_y;
int score = 0;
int direction = 'D'; // 默认向右

void moveSnake() {
    int newX, newY;
    switch (direction) {
        case 'U':
            newY = snake[HEAD].y - 1;
            break;
        case 'D':
            newY = snake[HEAD].y + 1;
            break;
        case 'L':
            newX = snake[HEAD].x - 1;
            break;
        case 'R':
            newX = snake[HEAD].x + 1;
            break;
    }
    
    if (newX >= 0 && newX < BOARD_SIZE && newY >= 0 && newY < BOARD_SIZE && snake[newY * BOARD_SIZE + newX] != HEAD) {
        for (int i = snake.length - 1; i > HEAD; i--) {
            snake[i] = snake[i - 1];
        }
        snake[HEAD].x = newX;
        snake[HEAD].y = newY;
        
        if (snake[HEAD].x == apple_x && snake[HEAD].y == apple_y) {
            score++;
            apple_x = rand() % BOARD_SIZE;
            apple_y = rand() % BOARD_SIZE;
        } else {
            apple_x = snake[HEAD].x;
            apple_y = snake[HEAD].y;
        }
    }
}

int main() {
    srand(time(NULL));
    apple_x = rand() % BOARD_SIZE;
    apple_y = rand() % BOARD_SIZE;
    
    while (1) {
        printf("Score: %d\n", score);
        for (int i = 0; i < BOARD_SIZE; i++) {
            for (int j = 0; j < BOARD_SIZE; j++) {
                if (i == snake[HEAD].x && j == snake[HEAD].y)
                    printf("H");
                else if (i == apple_x && j == apple_y)
                    printf("A");
                else
                    printf(".");
            }
            printf("\n");
        }
        moveSnake();
        getchar(); // 等待用户按键
        direction = getDirection(); // 获取并更新方向
    }
    return 0;
}

// 用户输入方向函数，实际项目可能需要更复杂的输入处理
char getDirection() {
    char input;
    scanf("%c", &input);
    return input;
}
