Summary
Throughout this chapter, we have deepened our understanding of the STL through the lens of std::vector and its interaction with various algorithms. We commenced with sorting vectors, where we explored the std::sort algorithm and its underlying engine, introsort, appreciating its O(n log n) efficiency. We progressed to searching within vectors, contrasting the conditions and efficiencies of linear and binary search techniques.
The chapter then guided us through effective vector manipulation, including transformation with std::copy and the considerations necessary to prevent performance degradation or logical errors. We learned to use custom comparators and predicates to extend the functionality of standard algorithms when working with user-defined structs and classes. Finally, we explored container invariants and iterator invalidation, acquiring strategies to maintain data integrity even in complex, multi-threaded environments.
Critically, this information provides us...
