贪吃蛇c语言程序代码简化版

贪吃蛇是一个经典的小游戏，其实现需要使用图形界面或者游戏引擎。如果您希望了解C语言实现的简化版贪吃蛇，可以参考下面的代码：

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

#define WIDTH 20    // 地图宽度
#define HEIGHT 20   // 地图高度
#define MAX_LENGTH (WIDTH * HEIGHT)    // 蛇的最大长度

int snakeX[MAX_LENGTH];     // 蛇的x坐标
int snakeY[MAX_LENGTH];     // 蛇的y坐标
int length = 3;             // 蛇的初始长度
int foodX, foodY;           // 食物的坐标
int score = 0;              // 得分
int direction;              // 蛇头的方向：1为上，2为下，3为左，4为右
int speed = 200;            // 蛇的速度

void initMap();             // 初始化地图
void initSnake();           // 初始化蛇
void generateFood();        // 生成食物
void move();                // 移动蛇
void updateDirection();     // 更新方向
void gameOver();            // 游戏结束

int main() {
    initMap();
    initSnake();
    generateFood();

    while (1) {
        move();
        Sleep(speed);
    }

    return 0;
}

void initMap() {
    system("cls");
    for (int i = 0; i < WIDTH + 2; i++) {
        printf("#");
    }
    printf("\n");

    for (int i = 0; i < HEIGHT; i++) {
        printf("#");
        for (int j = 0; j < WIDTH; j++) {
            printf(" ");
        }
        printf("#\n");
    }

    for (int i = 0; i < WIDTH + 2; i++) {
        printf("#");
    }
    printf("\n");

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

void initSnake() {
    snakeX = WIDTH / 2;
    snakeY = HEIGHT / 2;
    snakeX = snakeX;
    snakeY = snakeY + 1;
    snakeX = snakeX;
    snakeY = snakeY + 1;

    for (int i = 0; i < length; i++) {
        printf("@");
        gotoxy(snakeX[i] + 1, snakeY[i] + 1);
    }
}

void generateFood() {
    srand((unsigned)time(NULL));
    do {
        foodX = rand() % WIDTH;
        foodY = rand() % HEIGHT;
    } while (foodX == snakeX && foodY == snakeY);

    gotoxy(foodX + 1, foodY + 1);
    printf("*");
}

void move() {
    if (_kbhit()) {
        updateDirection();
    }

    int tailX = snakeX[length - 1];
    int tailY = snakeY[length - 1];
    gotoxy(tailX + 1, tailY + 1);
    printf(" ");

    for (int i = length - 1; i > 0; i--) {
        snakeX[i] = snakeX[i - 1];
        snakeY[i] = snakeY[i - 1];
    }

    switch (direction) {
        case 1:
            snakeY--;
            break;
        case 2:
            snakeY++;
            break;
        case 3:
            snakeX--;
            break;
        case 4:
            snakeX++;
            break;
    }

    if (snakeX == foodX && snakeY == foodY) {
        score++;
        length++;
        generateFood();
        if (speed > 50) {
            speed -= 10;
        }
    }

    if (snakeX < 0 || snakeX >= WIDTH || snakeY < 0 || snakeY >= HEIGHT) {
        gameOver();
        return;
    }

    for (int i = 1; i < length; i++) {
        if (snakeX[i] == snakeX && snakeY[i] == snakeY) {
            gameOver();
            return;
        }
    }

    gotoxy(snakeX[0] + 1, snakeY + 1);
    printf("@");

    gotoxy(WIDTH + 4, 2);
    printf("Score: %d", score);
}

void updateDirection() {
    char ch = _getch();
    switch (ch) {
        case 'w':
            if (direction != 2) {
                direction = 1;
            }
            break;
        case 's':
            if (direction != 1) {
                direction = 2;
            }
            break;
        case 'a':
            if (direction != 4) {
                direction = 3;
            }
            break;
        case 'd':
            if (direction != 3) {
                direction = 4;
            }
            break;
    }
}

void gameOver() {
    system("cls");
    printf("Game Over!\n");
    printf("Score: %d\n", score);
    system("pause");
    exit(0);
}

以上是简化版贪吃蛇的C语言代码。在这个代码中，我们使用了Windows API中的`gotoxy()`函数，来实现在控制台上输出蛇和食物。
