Files of the type cpp or files with the file extension. When crafting a new template class, you can place the implementation of the class within a separate cpp file as long as you create a trivial instantiation of that class within it.

Instead, we define the function using placeholder types, called template type parameters. Templates are parameterized by one or more template parameters, of three kinds.
