What are some common iterator patterns in C++?

Common iterator patterns in C++ include the Iterator, Reverse Iterator, and Const Iterator patterns.

Can you explain the Iterator pattern in more detail?

Sure! The Iterator pattern allows sequential access to elements in a collection without exposing the underlying structure.

What about the Reverse Iterator pattern?

The Reverse Iterator pattern enables traversal of a collection in reverse order, which is useful for certain algorithms.

Are there any specific use cases for these patterns?

Yes, they are often used in STL containers like vectors and lists to provide flexible and efficient element access.
