Re: [hlcoders] Dum C++ pointer question

[Varlock]

    A pointer is just a variable containing the address to a location in
memory, so it would be expected that assigning the pointer like that would
just make ob2 point to ob1. To do what you want to do, I would recommend a
copy constructor. You could also overload the assignment operator.

class CObject
{
public:
    // blah blah blah

    CObject( const CObject &copy );
};

CObject :: CObject( const CObject &copy )
{
    m_iInteger = copy.m_iInteger;
    m_flFloat = copy.m_flFloat;

    // assign any other values here
}

    I think that's about it. Watch out for pointers and strings in the copy
constructor, since you probably don't want to just assign them like above.
You probably want to use functions like strcpy and memcpy for those.
