Templates in C++

Templates in C++ allow writing generic and reusable code by defining a blueprint for functions or classes that work with any data type. They enable code reusability and type safety while avoiding redundancy. Templates come in different forms, including function templates, class templates, variadic templates, and template specialization.

Generic template / Function template

A generic template refers to a standard template that can work with any type, making code flexible and reusable.

Template Specialization

Template specialization allows customizing the behavior of a template for specific types. This is helpful when the generic template isn'tt suitable for certain cases, requiring a customized implementation for specific types.

Class template

Class templates allow defining generic classes that work with any data type.

Variadic template

Variadic templates allow handling an arbitrary number of template arguments using typename... Args.
