Multiple inheritance doubt

[pradeep]

Hello friends:

In the following setup,

class A {
...
};

class B {
...
};

class C : public A, public B {
...
}

void main()
{
A* x = new C;
delete (x);
}

Does the B part of x get deleted properly?

Thanks.

....and this is not C++ (even more so than it is not C).

Decide which language you're using, use it properly, and ask questions
about it in the right place.

Presumably you were trying to write an invalid program. You succeeded on
several counts. I merely identified the first problem.

Yes, provided A has a virtual destructor.

Please, direct your C++-related questions to a C++ newsgroup. This is a C
newsgroup. C language has no classes, inheritance, etc.

OK thanks for ur answer, can you explain more what's happening?

To Audrey Tasarevich, I'm writing in C/C++ so I think this group is a
good one for my question.

Thanks.

No, you are writing C++, that group is down the hall. You might get one
person's opinion here, you will get many there.

No, C and C++ are two different languages. C does not have multiple
inheritance. C++ has its own set of newsgroups, including
comp.lang.c++, where questions about multiple inheritance would be
appropriate.

"Antoninus Twink" wants you to think that comp.lang.c is an appropriate
place for questions about C++.

"Antoninus Twink" is lying to you.

There is no such language, nor is there any user 'ur'. There are C
and C++ languages, which are different. You are apparently using
C++, and your questions should go to comp.lang.c++. FUPs set.
