Summary
Iterators are objects that can point to elements in a range of elements and iterate through them using a set of operators. Depending on the properties supported by iterators, they are classified into five different categories: input, output, forward, bidirectional, and random-access. Iterators have arithmetic operators, inequality comparisons, compound assignment operations, and offset dereference operators, and can be used to access ranges non-sequentially.

Summary
This blog post provides an example of how to create an iterable range in C++ using an Input Iterator class. The postincrement operator is not correct, and the postincrement operator must be used to return the value at the iterator before the increment. Anthony Williams has provided a correction to the postincrement operator, and Andy Balaam has provided an example of how to write an iterator for an iterable range in C++11.

Summary
An iterator is an object that points to an element inside a container. Like a pointer, an iterator can be used to access the element it points to and can be moved through the content of the container. Each container in the C++ Standard Library provides its own iterator, as well as some methods to retrieve it

In computer programming, an iterator is an object that enables a programmer to traverse a container, particularly lists. Various types of iterators are often provided via a container's interface. Though the interface and semantics of a given iterator are fixed, iterators are often implemented in terms of the structures underlying a container implementation and are often tightly coupled to the container to enable the operational semantics of the iterator. An iterator performs traversal and also gives access to data elements in a container, but does not itself perform iteration (i.e., not without some significant liberty taken with that concept or with trivial use of the terminology).

This is a rant. C++17 is at our doorstep and we’re no closer to iterable enums. And what annoys me is that I coded a solution in a single day as proof of ...
