Help with solitaire game

-----------------------------------

OK so I am working on a project for my gr.12 cs class. The first part of the project is making a solitaire game playable by people.

My problem is that my program is crashing for no apparent reason.

#include 
#include 

#include "card.h"

using namespace std;

class Mouse {
public :
    int x, y;

    void add_card (Card *card);

    bool down, down_last;
    bool clicked();


protected :
    vector  cards;
};


void Mouse::add_card(Card *card) {


    cards.push_back(card);         //This is where it crashes!


}

bool Mouse::clicked() {
    return down && !down_last; //If the mouse is pressed down but wasnt pressed down the last time it was updated
}


I have double checked that it is passing a valid pointer to the function. It just seems that the vector "cards" is not accepting anything. Also if I output cards.size() before push_back is called even once it outputs 8. I can supply more details upon request.

Any help is appreciated :)


Edit: This class represents the users mouse. The vector 'cards' holds the cards that the user is currently dragging from one stack to another.

Don't you have to do something to initialize a vector? (Or is that done automatically in c++?)

When I call cards.push_back(), it should dynamically allocate memory as far as I'm aware. I have a nearly identical set up for the other classes that contain a vector or stack of pointers to Card objects.

I think you may have to specify a size for the vector.  I've had similar problems before

Already tried that, doesn't work. Not to mention it works perfectly fine in the other classes.

Found the problem and I hate myself for it...

Forgot to add Mouse mouse; to one of my main header files >.< It was only in the .cpp file.
