WebJun 9, 2024 · vector::rbegin () is a built-in function in C++ STL which returns a reverse iterator pointing to the last element in the container. Syntax: vector_name.rbegin () Parameters: The function does not accept any parameter. Return value: The function returns a reverse iterator pointing to the last element in the container. Webnext iterator in that data structure so depends whether sorted in ascending or descending order. An important info about the upper_bound used in various data structures: is that it will return the iterator pointing to the next iterator to which the number should be there also depends on the sorting order
WebMar 17, 2024 · The elements are stored contiguously, which means that elements can be accessed not only through iterators, but also using offsets to regular pointers to elements. This means that a pointer to an element of a vector may be passed to any function that expects a pointer to an element of an array.

WebJun 8, 2024 · Describes an iterator adaptor that satisfies the requirements of an output iterator. It inserts, rather than overwrites, elements into the back end of a sequence and thus provides semantics that are different from the overwrite semantics provided by the iterators of the C++ sequence containers.
