WebAug 16, 2024 · I wrote a simple iterator wrapper that can be used in e.g. std::find and std::copy and iterator pair constructors to search on and extract members from structs contained in an iterable range. It can probably be made to work with member functions accepting (copyable) arguments, but simple argumentless getters work fine as it is now. WebIterators are also useful for some functions that belong to container classes that require operating on a range of values. A simple but useful example is the erase function. The vector template supports this function, which takes a range as specified by two iterators -- every element in the range is erased. For instance, to erase an entire vector:
