It provides a very generic approach to traversing through the elements of a container. We use an iterator to iterate the container elements although we can use the conventional loops, iterators have the upper hand on iterating through a container. In C++, an iterator is an object like a pointer, pointing to the elements inside an array, list and any other data structure. Iterators are another powerful mechanism in C++ that helps you iterate over complex data structures like a tree and sets where we don’t have the indices of elements inside, like an array. Why We Can’t Dereference an Iterator in C++. ![]()
