Briefly explain early binding and late binding?

The word binding means the mechanism which the compiler uses to decide which function should be executed on which call.

Early binding: The function definition and function call are linked during compile time is known as early binding or static binding. This can be achieved using normal function.

Late binding: The function calls with the correct function definition at run time is known as late binding or dynamic binding. Dynamic binding can be achieved by using virtual function.
