This is what templates are for. You simply write the function as normal, but on the front you put template <class SOMETYPE> and in your code you write the type that the compiler has to fill in for you as SOMETYPE, so you get this: Templates are a tool for static polymorphism (see below) and generic programming. In addition, templates are a compile-time mechanism in C++ that is Turing-complete, meaning that any computation expressible by a computer program can be computed, in some form, by a template metaprogram prior to runtime. In summary, a template is a compile-time …Trait class that identifies whether U is a type assignable to T. The class inherits from integral_constant as being either true_type or false_type, depending on whether T supports being assigned U. Template parameters T, U Complete types, or void (possible cv-qualified), or an array of unknown bound. Member types Inherited from integral_constant:Writing documents can be a daunting task, especially if you’re not sure where to start.
