贪吃蛇，请问这个代码怎么实现死亡之后能询问是否继续，否退出，是的话重新开始游戏

#include<stdio.h> #include<string.h> #include<windows.h> #include<time.h> #include<conio.h> #define up 'w' #define down 's' #define left 'a' #define right 'd' #define stop 'P' void welcome(); //55开始界面 void Finish();

//157获取键盘信号 int Judge(); //270游戏结束判断 void MovingBody(); //172蛇的移动 void Eatting(); //223蛇吃到东西后的操作（伸长） void ChangeBody(int a, int b); //245蛇的坐标变换,后一个复制前一个STRUCT,a,b为head之前坐标 /*全局变量 + 预处理：*/ typedef struct Snakes { int x;
