Need help with Solitaire code

Yamraj (9)
Hi guys, I have been given the task to comment a code for solitaire which is broken into 3-4 header files. I will post each one seperately, and as I learn what each line of the code does, or each important function, I will post the next header file. So let's get started with the "card" header file.

}

std::string Card::Suit () {

#endif


Can someone please explain to me what each major function or structure is doing?

Thanks in Advance!

Card (std::string, std::string); // Creates the card given the suit and value
~Card (); // Cleans up memory when a card is destroyed
void Draw (BITMAP *, bool); // Draws the card with a bitmap picture.  It will either draw it in a "front" or "back" stype
void SetPos (int, int, int, int); // Positions the card. Do this before drawing
void Debug (BITMAP *); // Draws the "hit" region.  Probably used for debug only
bool OnMouse (); // returns whether the card was clicked
HitBox* Hit (); // Returns a pointer to a HitBox, whatever that is
int X (); // Returns the x position of the card
int Y (); // Returns the y position of the card
std::string Suit (); // Returns the suit of the card
int Num (); // Returns the value of the card
