c++面向对象简单贪吃蛇

好的，我可以为您提供一个简单的C++面向对象贪吃蛇游戏的代码示例，如下所示：

#include <iostream>
#include <conio.h>
#include <windows.h>
using namespace std;

const int width = 20;
const int height = 20;

class Snake {
private:
    int x, y;
public:
    Snake() {
        x = width / 2;
        y = height / 2;
    }
    void move(int dx, int dy) {
        x += dx;
        y += dy;
        if (x < 0) x = width - 1;
        if (x > width - 1) x = 0;
        if (y < 0) y = height - 1;
        if (y > height - 1) y = 0;
    }
    int getX() {
        return x;
    }
    int getY() {
        return y;
    }
};

class Fruit {
private:
    int x, y;
public:
    Fruit() {
        x = rand() % width;
        y = rand() % height;
    }
    int getX() {
        return x;
    }
    int getY() {
        return y;
    }
    void changePosition() {
        x = rand() % width;
        y = rand() % height;
    }
};

class Game {
private:
    bool gameOver;
    Snake snake;
    Fruit fruit;
public:
    Game() {
        gameOver = false;
    }
    void draw() {
        system("cls");
        for (int i = 0; i < width + 2; i++) {
            cout << "#";
        }
        cout << endl;

        for (int i = 0; i < height; i++) {
            for (int j = 0; j < width; j++) {
                if (j == 0) {
                    cout << "#";
                }
                if (i == snake.getY() && j == snake.getX()) {
                    cout << "O";
                } else if (i == fruit.getY() && j == fruit.getX()) {
                    cout << "F";
                } else {
                    cout << " ";
                }
                if (j == width - 1) {
                    cout << "#";
                }
            }
            cout << endl;
        }

        for (int i = 0; i < width + 2; i++) {
            cout << "#";
        }
        cout << endl;
    }
    void input() {
        if (_kbhit()) {
            switch (_getch()) {
                case 'a':
                    snake.move(-1, 0);
                    break;
                case 'd':
                    snake.move(1, 0);
                    break;
                case 'w':
                    snake.move(0, -1);
                    break;
                case 's':
                    snake.move(0, 1);
                    break;
                case 'x':
                    gameOver = true;
                    break;
            }
        }
    }
    void logic() {
        if (snake.getX() == fruit.getX() && snake.getY() == fruit.getY()) {
            fruit.changePosition();
        } else {
            snake.move(0, 0);
        }
    }
    void run() {
        while (!gameOver) {
            draw();
            input();
            logic();
            Sleep(50);
        }
    }
};

int main() {
    Game game;
    game.run();
    return 0;
}

这个程序使用了三个类：`Snake`、`Fruit`和`Game`。`Snake`类表示蛇，`Fruit`类表示水果，`Game`类表示整个游戏。在`Game`类的`run`函数中，程序会不断地循环执行`draw`、`input`和`logic`函数，直到游戏结束。`draw`函数用于绘制游戏界面，`input`函数用于处理用户输入，`logic`函数用于处理游戏逻辑。
