I need "comments" fo this whole code, for my better understanding. comment for every line. also i want this code to be separated in .cpp and. hpp files. thank you #include #include #include #include #include #include #define MAXSNAKESIZE 100 #define MAXFRAMEX 119 #define MAXFRAMEY 29 using namespace std; HANDLE console = GetStdHandle(STD_OUTPUT_HANDLE); COORD CursorPosition; void gotoxy(int x, int y){ CursorPosition.X = x; CursorPosition.Y = y; SetConsoleCursorPosition(console, CursorPosition); } void setcursor(bool visible, DWORD size) // set bool visible = 0 - invisible, bool visible = 1 - visible { if(size == 0) { size = 20; // default cursor size Changing to numbers from 1 to 20, decreases cursor width } CONSOLE_CURSOR_INFO lpCursor; lpCursor.bVisible = visible; lpCursor.dwSize = size; SetConsoleCursorInfo(console,&lpCursor); } class Point{ private: int x; int y; public: Point(){ x = y = 10; } Point(int x, int y){ this -> x = x; this -> y = y; } void SetPoint(int x, int y){ this -> x = x; this -> y = y; } int GetX(){ return x; } int GetY(){ return y; } void MoveUp(){ y--; if( y < 0 ) y = MAXFRAMEY; } void MoveDown(){ y++; if( y > MAXFRAMEY ) y = 0; } void MoveLeft(){ x--; if( x < 0 ) x = MAXFRAMEX; } void MoveRight(){ x++; if( x > MAXFRAMEX ) x = 0; } void Draw(char ch='O'){ gotoxy(x,y); cout<x = x; p->y = y; } int IsEqual(Point * p){ if( p->x == x && p->y ==y ) return 1; return 0; } void Debug(){ cout<<"("<
