I am currently creating a sqaure list and one of the requrements is to overload the the pre and post ++ operator.
Ive tried overloaded the ++operator in my .hpp file to increment an interator. But when calling the ++operator it does not call the overloaded code and just uses the default.
I.e. you always return begin() + 1. However I think you should get begin() + 1 after the first increment then begin() + 2 after the second increment and so on.
