I've Googled this and read many posts, but there are so many different answers that all make logical sense that I was wondering if an expert on the topic could demystify this question.
Some say that there is no return because there is no way to return - the syntax prohibits it - yes, this makes sense, but I believe that all functions have to return something, no? Others say that the constructor sort of returns the newly created object itself, which seems to make sense since the assignment operator is used on the constructor. Still others have other interesting explanations.
Constructors aren't called like other functions, so they don't return like other functions. They execute as a side-effect of certain constructs (cast, new, variable definition, ctor-initializer-list, pass-by-value, return-by-value).
