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 function [`std::forward`](http://en.cppreference.com/w/cpp/utility/forward), defined in the header `<utility>`, empowers you to write function templates, which can identically forward their arguments. Typical use cases for `std::forward` are factory functions or constructors. **Factory functions** are functions which create an object and must therefore identically pass the arguments. Constructors often use their arguments to initialize their base class with identical arguments. So `std::forward` is the perfect tool for authors of generic libraries:

Now, we'll learn about the way std::forward helps us create generic function templates.
