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 in c++ this can be achieved using template parameters a template parameter is a special kind of parameter that can be used to pass a type as argument just like regular function parameters can be used to pass values to a function template parameters allow to pass also types to a function
For cases such as this, C++ has the ability to define functions with generic types, known as function templates. Defining a function template follows the same syntax as a regular function, except that it is preceded by the template.The template parameters are a series of parameters separated by commas. These parameters can be generic template types by specifying either the class or typename keyword followed by an identifier.t makes no difference, and T is actually a quite common template parameter name for generic types. In the example above, we used the function template sum twice. The first time with arguments of type int, and the second one with arguments of type double.
