求大神给我详细讲解下面的c++贪吃蛇程序

#include

using namespace std;
// 刷新当前屏幕
inline void Refresh(char q[][22], int grade, int gamespeed){
    system("cls");     //  清屏
 int i,j;
 cout << endl;
 for(i=0;i      cout   for(j=0;j    cout         if(i==0) cout         if(i==4) cout         if(i==6) cout   cout  }
}
int main(){
    char tcsQipan[22][22];     //  贪吃蛇棋盘是一个二维数组(如22*22,包括墙壁)
    int i,j;
    for(i=1;i         for(j=1;j             tcsQipan[i][j]=' ';     //     初始化贪吃蛇棋盘中间空白部分
    for(i=0;i         tcsQipan[0][i] = tcsQipan[21][i] = '-';      //初始化贪吃蛇棋盘上下墙壁
    for(i=1;i         tcsQipan[i][0] = tcsQipan[i][21] = '|';      //初始化贪吃蛇棋盘左右墙壁
    int tcsZuobiao[2][100];     //蛇的坐标数组
    for(i=0; i         tcsZuobiao[0][i] = 1;
        tcsZuobiao[1][i] = i + 1;
    }
    int head = 3,tail = 0;
    for(i=1;i         tcsQipan[1][i]='*';    //蛇身
    tcsQipan[1][4]='#';       //蛇头
    int x1, y1;           // 随机出米
    srand(time(0));
    do{
  x1=rand()%20+1;
  y1=rand()%20+1;
 }while(tcsQipan[x1][y1]!=' ');
 tcsQipan[x1][y1]='*';
 cout  long start;
    int grade = 1, length = 4;
    int gamespeed = 500;  //前进时间间隔
 for(i=3;i>=0;i--){
  start=clock();
  while(clock()-start<=1000);
  system("cls");
  if(i>0)
   cout << "\n\n\t\t进入倒计时:" << i << endl;
  else
   Refresh(tcsQipan,grade,gamespeed);
 }
    int timeover;
    char direction = 77;  // 初始情况下,向右运动
    int x,y;
    while(1){
        timeover = 1;
        start = clock();
        while((timeover=(clock()-start<=gamespeed))&&!kbhit());
             //如果有键按下或时间超过自动前进时间间隔则终止循环
        if(timeover){
            getch();direction = getch();
        }
        switch(direction){
        case 72: x= tcsZuobiao[0][head]-1; y= tcsZuobiao[1][head];break;     // 向上
        case 80: x= tcsZuobiao[0][head]+1; y= tcsZuobiao[1][head
