Re: <pair> Class Derived from Other Class?
"Jonathan Wood" <firstname.lastname@example.org> wrote in message
I need to create a class that is based on the <pair> template.
pair<const char*, CODER_FACTORY>
But the class needs to be derived from another class, CNode.
I know I can use multiple inheritance, but is there a way to do that
so a method expecting a CNode pointer can accept a pointer to an
instance of this class?
You don't need to do anything special.
At the very least, it must surely matter the order that I list the
No, it doesn't matter. The compiler will generate code to adjust pointer
value as needed when performing conversion.
It will be critical that the CNode members match
the arrangement of single inheritance from CNode.
They will. You don't need to do anything special.
I'm not sure if
that arrangement is part of the C standard or not.
No. C doesn't have classes or inheritance. But it is part of C++
