Inheritance in C++ (urgent)

[VB_HELP]

I have a Class Account with some functions like
withdraw , deposit, Print as public functions
and I have also classes called Checking , Savings which are inherited from the above ones . I have overided the print function of Class Account in both Checking and Savings classes.
But my below code does not work properly.

Account *A[10];

A[1] = new Checking();
A[2] = new Savings();

When I reference A[1]->print() sometimes it is giving some error or just printing from Account but not coming from Checking or savings
Can Any one Help me

thanks

For this you need to use virtual inheritance, which I explained somewhere else....do a search for Base and Derived

Make the public functions that get overridden virtual:

class Base {
public:
    virtual void Print() { ... }
};

Thanks,
I guess it works out

Like:

class CObject
{
public:
CObject();
~CObject();

virtual void draw() {}
};

class CCube : public CObject
{
public:
CCube();
~CCube();

void Draw()
{
// Drawing Code
}
};

Sorry if its a bit late etc but what the hell

Don't see why people put "C" in front of class names, but oh well

Anyway, that's just normal inheritance. Virtual inheritance is calling a derived class member function through a base class pointer. The compiler magically knows to call the right one Cool really
