WebFeb 3, 2024 · An iterator is an object designed to traverse through a container (e.g. the values in an array, or the characters in a string), providing access to each element along the way. A container may provide different kinds of iterators. For example, an array container might offer a forwards iterator that walks through the array in forward order, and a ... WebFirst arguments is iterator pointing to the start of array arr. Second arguments is iterator pointing to the end of array arr. The third argument is the string value ‘strvalue’. It returns an iterator pointing to the first occurrence of the string strvalue in the array arr.
