Such "things" in C++ are objects of ... Web3 Aug 2024 · The iterators come in handy when we use certain operations that require an argument for positioning. The two most used functions returning iterator values are: 'v.begin ()' - It returns an iterator to the first vector in a 2-D vector. 'v.end ()' - It returns an iterator to the end of the 2-D vector.
