贪吃蛇游戏c++面向对象代码

好的，以下是一个简单的贪吃蛇游戏的 C++ 面向对象代码示例：

#include <iostream>
#include <vector>
#include <conio.h>
#include <windows.h>

using namespace std;

const int WIDTH = 20; // 游戏界面宽度
const int HEIGHT = 20; // 游戏界面高度
const int FPS = 10; // 游戏帧率

// 定义坐标点结构体
struct Point {
    int x;
    int y;
};

// 定义运动方向枚举类型
enum Direction {
    UP,
    DOWN,
    LEFT,
    RIGHT
};

// 定义贪吃蛇类
class Snake {
public:
    Snake(Point head) {
        body.push_back(head);
        direction = RIGHT;
    }
