Unhandled Exception Error

Well, I'm pretty new here... Anyways, I have this error that I just can't fix (I've been looking at it for a week), so do you think you can help me? The problem is that when I run the program(A Poker game I'm working on) it pops up with a "Unhandled Exception Error" when I try to print out a card class (You'll see in the code). What I want to do is to circumvent the Unhandled Exception in such a way that it will still work. I think the error is caused by a pointer but I have no idea how... The code is a bit long and without many comments... Thanks in advance. BTW: It's loosely based on the BlackJack game in the Beginning C++ Game Programming book.

Try changing your card class ostream to this:

ostream& operator<<(ostream& os, const card& aCard){	string suits[]={"Clubs", "Hearts", "Diamonds", "Spades"};	string ranks[]={"", "Ace", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};		os << ranks[aCard.cRank] << " Of " << suits[aCard.cSuit];	return os;}

The problem was that you were trying to assign a null value to a stack variable (non-pointer).

so this:

string ranks[]={0, "Ace", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};

needs to be this:

string ranks[]={"", "Ace", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};

Hope this helps! Good luck!

Thank You!
It worked! The only thing is why did it work? I want to be able to fix it again if it ever happens.
//EDIT
Whoops! Didn't see your explanation...

To be a bit more accurate: When you initialize the string array, the generated code makes an array of std::string objects, and attempts to initialize each using the char* that's provided to it. (string literals in double quotes are char*'s, not std::strings). The way this works is that the std::string constructor looks for data starting at the indicated pointer, and tries to copy it into its buffer. Given a null pointer - boom.
