Mastering Iterators with std::vector

In this chapter, we will gain a deeper exploration of std::vector, focusing on the intricacies of iteration. This chapter equips us with the knowledge to handle the ins and outs of vector traversal. Mastering these core areas bolsters the efficiency and reliability of one’s C++ code and provides insights into the underpinnings of dynamic array behavior, which is critical for effective C++.

In this chapter, we’re going to cover the following main topics:

• Types of iterators in the STL
• Basic iteration techniques with std::vector
• Using std::begin and std::end
• Understanding iterator requirements
• Range-based for loops
• Creating a custom iterator
