It is used to avoid the ambiguity problem in c++ (multiple
inheritance).
when sub class inherits same members from 2 base classes.
compiler dont know which variable has assigned the value.
If u declare the class as virtual only one time is
inherited in its derived class.A copy will never get
inherited.
concept of virtual methods is different purpose.
like how we have abstract key word in java,we can acheive
method abstraction using virtual keyword before a method.
please select no if u really know this answer is wrong.
people with out having knowlede saying simple know hurts
the technical world.
