Function overriding occurs when a derive class has a definition of one or more members of base class.

 Runtime Poly

Function overriding occurs when a derive class has a definition of one or more members of base class.

Advantages of Data Abstraction

Avoid code duplication and inc. reusability. Can change internal implementation of class independently.

Structure vs class

Most important difference is

security. A Structure is not secure and cannot hide its member function and variable while class

is secure and can hide its programming & designing details.

Local classes in C++:

A class declared inside a function becomes local to that function and is called local class.

All the methods of local class must be defined inside the class only.

Virtual function and Runtime Polymorphism: A virtual function is a member function. which is declared with a base class and

redefined Coverriden) by derived class. functions are declared with virtual Keyword base class.
