Re: [Dev-C++] Passing by value or reference to constructorinitialiation list

[Daniel G. <sp...@ho...>]

Well I think passing by reference is better because the objects could be 
large, which means more on the stack and thus more overhead, but are there 
any side effects to passing by reference to the constructor in this way?

If you want to avoid the construction and destruction of temporary object=
s
(the function arguments) then pass by reference. Usually for non-built in
types we pass by reference.=0D
