Explore the full potential of C++ by mastering the standard library.

Become a C++ Programmer

The C++ standard library is a collection of all the tools and utilities available in C++. It received its latest update in 2017, known as C++17. The update introduces many new features that further optimize our code. This module will help us fully grasp C++ and use it to its full potential.

C++ Standard Library

The insertion (`insert` and `emplace`) and deletion (`erase`) of elements in associative containers is similar to the rules of an [std::vector](https://www.educative.io/courses/cpp-fundamentals-for-professionals/vectors). For an associative container that can have a key only once, the insertion fails if the key is already in the container. Additionally, ordered associative containers support a special function `ordAssCont.erase(key)`, which removes all pairs with the `key` and returns their number. See the usage of the function below.

In associative containers, values are inserted and deleted based on the keys they have.
