Forward checking algorithm

WebApr 25, 2024 · Forward iterators are one of the five main types of iterators present in C++ Standard Library, others being Input iterators, Output iterator, Bidirectional iterator and Random – access iterators. Forward iterators are considered to be the combination of input as well as output iterators. It provides support to the functionality of both of them.
