What are containers and iterators in C++?

Can you explain what containers are in C++?

Sure! In C++, containers are data structures that store collections of objects. They manage the storage and organization of data.

What types of containers are available in C++?

C++ offers several types of containers, including vectors, lists, sets, maps, and arrays, each with different use cases.

How do iterators work with these containers?

Iterators are objects that allow you to traverse the elements of a container. They provide a way to access elements without exposing the underlying structure.

Can you give an example of using an iterator with a vector?

Certainly! You can use a for loop with an iterator to access elements in a vector like this: for(auto it = vec.begin(); it != vec.end(); ++it) { std::cout << *it; }.
