Summary

In this chapter, you have learned the foundational aspects of std::vector in C++ STL. The chapter began by explaining the significance of std::vector, highlighting its advantages over C-style arrays, particularly regarding memory management and ease of use. The chapter thoroughly compared C-style arrays and std::vector, demonstrating how std::vector facilitates dynamic size adjustment and safer memory operations.

Next, you were guided through the processes of declaring and initializing vectors. You learned how to declare std::vector and initialize these instances using different methods. The chapter then explored the myriad ways of accessing elements within std::vector, from random access to accessing the first and last elements, and underscored the importance of understanding vector size.

Further, the chapter delved into the intricacies of adding and removing elements. This section illuminated the best practices for modifying the contents of a vector, including when...
