difference between class B and Class C

[Pallav singh]

what is the difference between class B and Class C w.r.t. void func( )
{ }


Class A{
Public :
Virtual void func( ){ }
}

Class B : public A{
Public :
Virtual void func( ){ }
}

Class C : public A{
Public :
void func( ){ }
}

Class C : public A{

This looks like a homework assignment.

Since the code contains numerous typos you haven't tried this.

The best way to proceed is to try it.

Is is something related to Sharing / Non-sharing of VTBL ?

A function once virtual, always a virtual!

Nope

A vtbl is something you should never be concerned about directly.
It's an implementation detail at best. Since the Standard doesn't
require a vtbl, an implementation is free not to provide one.

As has been mentioned before, I (and others) can imagine implementations
of varying quality which provide no vtbl at all.

Correction. A vtbl is something you should never be concerned about
directly, unless you are writing a compiler.
