Useful Functions
Explore the essential C++ global functions that simplify iterator handling. Understand how to use functions like std::begin, std::end, std::next, std::prev, and std::advance to navigate and modify containers efficiently. This lesson prepares you for practical iterator application in algorithms and data manipulation.

The global functions std::begin, std::end, std::prev, std::next, std::distance, and std::advance make handling of the iterators a lot easier. Only the function std::prev requires a bidirectional iterator. All functions need the header <iterator>. The table gives an overview:
