A Forward Iterator is a type of iterator that allows you to traverse a collection, such as a list or an array, in a single direction—typically from the beginning to the end. This means you can access each element one at a time, moving forward through the collection, but you cannot go backward. Forward iterators are commonly used in programming languages like C++ and Python to simplify the process of accessing elements in data structures. These iterators support basic operations such as incrementing to the next element and dereferencing to access the current element. They are particularly useful in algorithms that require sequential access to elements, making them an essential tool in the realm of computer science and software development.
