Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type. Function Templates We write a generic function that can be used for different data types. Function templates are special functions that can operate with generic types. This allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type. Or Function Template Template is a method for writing a single function or class for a family of similar functions or classes in a generic manner. When a single function is written for a family of similar functions, it is called as ‘function template’. Class Templates Like function templates, class templates are useful when a class defines something that is independent of the data type. Or class template: In addition to function templates, C++ also supports the concept of class templates. By definition, a class template is a class definition that describes a family of related classes. C++ offers the user the ability to create a class that contains one or more types that are generic or parameterized. The manner of declaring the class template is the same as that of a function template. The keyword template must be inserted as first word for declaring a class template.
