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

## Introduction
To be honest, [std::weak_ptr](http://en.cppreference.com/w/cpp/memory/weak_ptr) is not a classic smart pointer, since it supports no transparent access to the resource; it only borrows the resource from an `std::shared_ptr`.

std::weak_ptr is the last component of the smart pointers family. Its purpose is limited compared to the other smart pointers, and we will examine why in this lesson.
