Hey everyone
Yeah so I have this program that I'm coding and when I compile it crashes (I don't know where the source of the error is). So I've parsed through it many times to no avail. I'm using the Borland C++ compiler and the debugger that comes with it. But this particular debugger doesn't seem to be too good. Anyone know of any that I could use?
If someone could have a look at my code quickly (much <3 if you can) or point me to a good debugger that could help me find this memory leak I will be greatfull.
Here is my code, in which the problem is...
This is the start of the .h file
class Player{
protected:
char* PlayerName_;//a string containing the Player's name
Card* CardsDealt_;
//an array representing the cards initially dealt to the Player
int Dealt_; //an integer containing the number of cards dealt to the Player
void Set(const char*,const Card*,int); //private member function, used to set the object (instantiat), should be called all the constructors
void Init(const Player&); //private member funtion called by copy constructor and assignment operator
public:
Player(); //defualt constructor, PlayerName = "unknown" and the Player initially holds no cards by calling the Set private member function
Player(const char*,const Card*,int); //3 argument constructor, takes in a char value, a Card value and an int and calls the Set private member function
Player(const Card*,int); //2 argument constructor, takes in a Card value and an int, in this case the value of PlayerName = "Unknown", calls the Set private member function
Player(const Player&); //copy constructor
~Player(); //destructor
void Deal(const Card cardsdealt[],int numcards); //function recieves an array const Card cardsdealt[] (represents the cards dealt to the Player) and an int numcards (number of cards dealt). This function replaces any cards currently held by the player with the cards in the cardsdealt array
void GetLowest(Card& c) const; //function recieves a reference to a Card, then finds lowest Card that the Player holds and then places the lowest Card's value into the Card refered to by c
int numcards() const; //query that returns the number of cards held
int GetCards(Card cardsheld[],int maxsize) const; //function copies held by Player into cardsheld array. If maxsize is less than the number of cards held by the Player, only copy maxsize cards. Function returns number of cards copied into the cardsheld array
const char* name() const; //function returns the name of the Player
void Print() const; //function prints the card held by the Player. Cards must be printed in a SORTED manner from low to high
Player& operator=(const Player&); //assignment operatorThis is the end of the .h file
