CPP Iterators provide powerful abstractions for traversing and manipulating containers in the CPP STL. They are categorized into input iterators, output iterators, forward iterators, bidirectional iterators, and random-access iterators. These iterators support low-level control, high performance, and seamless integration with CPP algorithms. The following sections compare and contrast their equivalents across various programming languages.
