The Four Polymorphisms in C++.
When people talk about polymorphism in C++ they usually mean the thing of using a derived class through the base class pointer or reference, which is called subtype polymorphism. But they often forget that there are all kinds of other polymorphisms in C++, such as parametric polymorphism, ad-hoc polymorphism and coercion polymorphism.
These polymorphisms also go by different names in C++,
Subtype polymorphism is also known as runtime polymorphism.
Parametric polymorphism is also known as compile-time polymorphism.
Ad-hoc polymorphism is also known as overloading.
Coercion is also known as (implicit or explicit) casting.
Ad-hoc polymorphism allows functions with the same name act differently for each type. For example, given two 'int' values and the '+' operator, it adds them together. Given two 'std::strings' it concatenates them together. This is called overloading.

Then how it would be ad-hoc? If ad-hoc for operator overloading virtual used for overloading of functions.
