Re: [Dev-C++] (code correction) Help with vectors

Mike,

As like as all of the recent messages I've posted to this list, sorry for this much late answer. I was too busy as this thread was going on, but I saved it till a time I can answer it, i.e. now!

Although not wrong, but the principle of const-correctness tells us that "it" must be of type "cons_iterator" rather than just "iterator."

No, not necessarily! The types of vector<>::iterator, and vector<>::const_iterator are, as per the Standard, implementation-specific. That is, although they are most likely to be implemented using pure pointers, they are not needed to be so. In fact, they are some widely-used implementations of STL (such as STLPort) which do not implement the above stuff using pure pointers.
