What is the difference between a const_iterator and an iterator and where would you use one over the other?
const_iterators don’t allow you to change the values that they point to, regulariterators do.As with all things in C++, always prefer
const, unless there’s a good reason to use regular iterators (i.e. you want to use the fact that they’re notconstto change the pointed-to value).
