What are some common iterator algorithms in C++?

What are some common iterator algorithms in C++?

In C++, common iterator algorithms include std::begin, std::end, std::next, std::prev, and std::advance. They help in navigating through containers.

Can you explain how std::next works?

Certainly! std::next takes an iterator and an optional integer offset, returning a new iterator that is advanced by that offset from the original.

What about std::for_each? How is it used with iterators?

std::for_each applies a function to each element in a range defined by two iterators. It's useful for performing operations on container elements.

Are there any iterator algorithms for searching?

Yes! Algorithms like std::find, std::find_if, and std::binary_search can be used to search for elements in a range defined by iterators.

Can you give an example of using std::find?

Sure! You can use std::find like this: std::find(vec.begin(), vec.end(), value); which returns an iterator to the first occurrence of value in the vector.
