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
if you insist on both the template being generic and having the definition of your template class somewhere else you can put the definition into another header file just call it something like this template impl h and include this template h in this template impl h then in your source file instead of # include this template h you write # include this template impl h
