In mathematics, the term generating function is used to describe an infinite sequence of numbers (a n) by treating them as the coefficients of a series expansion. The sum of this infinite series is the generating function.
Virtual functions ensure that the correct function is called for an object, regardless of the expression used to make the function call. Suppose a base class contains a function declared as virtual and a derived class defines the same function. The function from the derived class is invoked for objects of the derived class, even if it is called using a pointer or reference to the base class.
