• A. Classes
• B. Functions
• C. Class and function
• D. None of these

Answer 1

The correct option is C Class and function

A template can be used to create a family of Class and function.

Templates are a feature of the C++ programming language that allows functions and classes to operate with generic types. This allows a function or class to work on many different data types without being rewritten for each one.

Function templates:- 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.

Class template:- A class template by itself is not a type, or an object, or any other entity.
