This wonderful book describes working with containers, algorithms, helper classes, lambda expressions and other interesting tools that modern C++ is rich in. Having mastered the material, you will be able to radically reconsider your usual approach to programming. The advantage of the publication is its detailed description of the standard C++ template library, STL. Its latest version was released in 2017. In the book you will find more than 90 extremely realistic examples that demonstrate the full power of STL. Many of them will become basic building blocks for solving more general problems.
