It sequentially uses this iterator for input operations. In other words, you can say that it is used to read the values from the container. WebApr 20, 2024 · 1. I have extended a custom list class I have been working on with a Iterator class. I have not used std::iterator as a base class as it will be deprecated in C++17. There is some debate as to whether to use std::iterator_traits as a base class instead. I have decided to create my own from scratch.
