WebLearn C++ - Reverse Iterators. Example. If we want to iterate backwards through a list or vector we can use a reverse_iterator.A reverse iterator is made from a bidirectional, or random access iterator which it keeps as a member which can be accessed through base()..

WebIterate over a map in C++. This post will discuss how to iterate over a map in C++. The std::begin and std::end function returns an iterator pointing to the first element and the one-past-the-last element in the sequence. We can iterate over a map that starts with std::begin and ends at std::end, as shown below: 1. 2. 3. Webmap [A]=X map [B]=Y map [C]=Z. if you iterate for (map:iterator it=begin...) you'll get.
