CPP Iterators Equivalents: Compare and Contrast

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.
