Views as Data Members for Custom Iterators

Read Original

This technical article details the implementation of a custom iterator for flattening a 2D vector (vector of vectors) in C++. It first presents a manual solution tracking inner and outer indices, then demonstrates a modernized version leveraging C++20's ranges and join views to simplify the code while maintaining the required iterator interface with next() and has_next() methods.
