Operator overloaded

[Guest_imported]

hi..
i have some doubts in operator overloading... plz help me out.
I'm having a BaseClass and DerivedClass which is deriving publicly.
Now i'm having overloaded operator methods in class BaseClass which includes ( + , - , * , / , == )
Ive also overloaded the '=' operator which takes a const int as argument!
Now in the application when i try to assign an int to the Derived Object, the compiler gives me an error saying that no overload match is found! ...
but the overloading of '=' works fine when i define it at the DerivedClass level...
Can anyone explain it to me why is it so...
I use aCC compiler under HP-UX..
thanx in advance...
c ya

Try to overload the operator as a friend function (outside your class)

Also, you need to declare the operators "virtual" if they are not friend functions. That way, the correct one will be called in DerivedClass when you reference it from a BaseClass pointer.

For more info on this, check out Effective C++ by Scott Meyers. It goes into this in great detail.
