如何用C++还原经典贪吃蛇

Hi,大家好。
这是我在CSDN写的第一篇文章，希望大家喜欢
贪吃蛇的代码如下（仅供参考…）

typedef struct Snakebody
{
 int x, y;//身体的坐标
 struct Snakebody *next;//结构指针
}Snakebody;//先来创建保持身体的链表，贪吃蛇的核心代码就是该如何保存蛇的身体
typedef struct Snakexy
{
 int x;
 int y;
}Snakexy; //记录食物坐标
int sum = 0;     //计算得分
int JudgeSum = 0;    //判断是否加快
int Hard = 0;     //计算难度
int Pause = 200000000;   //暂停速度(移动速度)
int JudgeDirection = 4;   //判断方向
int * PJ = &JudgeDirection;  //用指针传值判断移动方向
Snakebody *Phead = NULL;  //存储着整个蛇身 不可更改
Snakebody *Phead_1 = NULL;  //指向蛇身
Snakebody *Pbady = NULL;  //创建节点
Snakebody *end = NULL;   //尾节点
Snakexy * Food = NULL;          //保存食物位置
void Front();                   //游戏开始页面1
void Jfood();     //检测是否吃到食物1
void Jwall();     //检测蛇头是否撞墙1
void Jsnake();     //检测蛇头是否撞到蛇身1
void ISnake();     //初始化蛇身1
void DeawMap();     //绘制地图1
void FoodRand();    //生成食物1
void ControlMove();    //控制移动和暂停1
void MoveCursor(int x, int y); //移动光标1
void Move();     //游戏运行1
void Showf();                   //显分数以及难度1
void Free();                    //释放内存
int main()
{
 Front();
 SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_GREEN);//绿
 DeawMap();
 Showf();
 SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_INTENSITY);// 暗白
 MoveCursor(34, 10);
 printf("↑");
 MoveCursor(31, 11);
 printf("使用←↓→来控制");
 MoveCursor(31, 12);
 printf("蛇的移动，撞墙游");
 MoveCursor(31, 13);
 printf("戏结束，每5分增 ");
 MoveCursor(31, 14);
 printf("一个难度(速度)");
 ISnake();
 FoodRand();
 MoveCursor(40, 20);
 Move();
 return 0;

好看吗？
这只是部分…（作者貌似看到的社会的险恶…）

然后这里说一下，如果报错可能是你的版本和我的版本不一样。
也有可能是你用C++的代码复制到python那儿去了（本人萌新时干的事）
