C++ Concept Map

Polymorphism

Polymorphism literally means "many shapes". It refers to the properties of a language which alter the normal meaning of a language construct.

C++ exhibits four kinds of polymorphism:

overloaded functions
the definition attached to a function name is altered according to the number of type of its parameters (its signature)
sub-type expressions
the evaluation of an expression is altered according to the inheritance relationship between classes
generic classes (and functions)
the declaration of a class is altered according to the value of compile-time parameters
dynamic binding of functions
the evaluation of an function call expression is altered according to the actual type of the caller object
