Virtual, as the name implies, is something that exists in
effect but not in reality. The concept of virtual function
is the same as a function, but it does not really exist
although it appears in needed places in a program. The
object-oriented programming language C++ implements the
concept of virtual function as a simple member function,
like all member functions of the class.
The functionality of virtual functions can be over-ridden
in its derived classes. The programmer must pay attention
not to confuse this concept with function overloading.
Function overloading is a different concept and will be
explained in later sections of this tutorial. Virtual
function is a mechanism to implement the concept of
polymorphism (the ability to give different meanings to one
function).
