What is Binding • Binding refers to linking of a function call to the code of function to be executed in response to the function call.

Types of Binding • Static Binding or Early Binding. • Dynamic Binding or Late Binding

Static Binding or Early Binding • Early binding - Assigning values to variables during design time or exposing object model at design time. • Early binding (also called static binding) means the compiler is able to directly associate the identifier name (such as a function or variable name) with a machine address.

Dynamic Binding or Late Binding • Bind the object library in code at run-time.

What is Virtual Function • Virtual functions are defined in Base Class and implemented in the Derived Class. • A virtual function is a member function you may redefine for other derived classes. • Declared with keyword virtual

Pure Virtual Function A Pure Virtual Function declared with no definition base class contains no implementation at all
