Overview of this book

While the Standard Template Library (STL) offers a rich set of tools for data structures and algorithms, navigating its intricacies can be daunting for intermediate C++ developers without expert guidance. This book offers a thorough exploration of the STL’s components, covering fundamental data structures, advanced algorithms, and concurrency features. Starting with an in-depth analysis of the std::vector, this book highlights its pivotal role in the STL, progressing toward building your proficiency in utilizing vectors, managing memory, and leveraging iterators. The book then advances to STL’s data structures, including sequence containers, associative containers, and unordered containers, simplifying the concepts of container adaptors and views to enhance your knowledge of modern STL programming. Shifting the focus to STL algorithms, you’ll get to grips with sorting, searching, and transformations and develop the skills to implement and modify algorithms with best practices. Advanced sections cover extending the STL with custom types and algorithms, as well as concurrency features, exception safety, and parallel algorithms. By the end of this book, you’ll have transformed into a proficient STL practitioner ready to tackle real-world challenges and build efficient and scalable C++ applications.

Checking conditions

The elegance of the C++ STL doesn’t just lie in its vast assortment of containers and algorithms. It also resides in its fine-tuned ability to let developers efficiently check and validate data using condition-based operations. With the might of predicate functions, these operations empower programmers to answer questions such as Does this dataset hold a particular property? and Are all elements in this range positive?

One of the most intuitive and fundamental operations is std::all_of. With this algorithm, you can check if all elements in a range satisfy a given predicate. If you had a list of students’ grades, you could use std::all_of to see if all grades were positive (and they should be!).

By contrast, its counterpart std::none_of checks if none of the elements in a range satisfy a given predicate. Let’s say you’re working with a list of student grades and want to ensure that no one has scored below passing marks. In this...
