Inclusion polymorphism
WebNov 2, 2014 · Polymorphism in C++ is more specifically termed “inclusion polymorphism” or “subtype polymorphism”. Overloading in C++ is a type of polymorphism, called ad hoc polymorphism. So, going back to the quote in the book – it is entirely correct, but causes confusion because the author does not distinguish between polymorphism as a general ... In programming language theory and type theory, polymorphism is the provision of a single interface to entities of different types or the use of a single symbol to represent multiple different types. The concept is borrowed from a principle in biology where an organism or species can have many different forms or stages. The most commonly recognized major classes of polymorphism are:

This can be summarised using the following See more In type theory the concept of subsumption is used to define or evaluate whether a type S is a subtype of type T. A type is a set of values. The set can be described extensionally by listing all the values, or it can be described intensionally by stating the … See more Width and depth subtyping Types of records give rise to the concepts of width and depth subtyping. These express two different ways of obtaining a new type of record that allows the same operations as the original record type. Recall that a record … See more Subtyping and inheritance are independent (orthogonal) relationships. They may coincide, but none is a special case of the other.
