Answer Posted / abhishek ajmera
When we declare a pure virtual function like this:-
Virtual PureVirtualFunction()=0;
This indicates compiler to reserve a slot for Function in VTABLE but don’t put an address in that particular slot. If only one function in a class is declared as pure virtual, the VTABLE is incomplete.
If the VTABLE for a class is incomplete, compiler cannot safely create an object of a pure abstract class, so you get an error message from the compiler if you try to make an object of a pure abstract class. Thus, the compiler ensures the purity of the abstract class, and you don’t have to worry about misusing it.
