WebMar 12, 2024 · I've not seen an indexing operator on an iterator before, but you could simplify it just by using the programmer's expectation: const T& operator [] (int index) { return * (*this + index); } Note that the assert () is okay for documenting invariants, but very poor for argument checking. Use a std::size_t for sizes and indexes
