This course will walk you through the newest version of C++ 20, C++ Concepts.

You will go through one of the most significant new features in C++20, which is Concepts. Concepts allow you to create compiler-checked criteria for template parameters, revolutionizing the way you think about and develop generic code. You can use them to provide both syntactic and semantic requirements. They also allow you to explicitly express your goal in the type system. If something goes wrong, you'll get a clear error message from the compiler.

While useful, Concepts can be difficult to apply and even confusing sometimes. This course provides you with the knowledge you need to overcome these obstacles and move on to more complex topics.

Let's get started.

C++ Concepts: Improve Type Safety with C++ 20

A type that is totally ordered must have _____ of its members totally ordered.

A type that is totally ordered must have _____ of its members totally ordered.

What kind of conversion is possible through `std::convertible_to`?  

What kind of conversion is possible through <code>std::convertible_to</code>?

the other five special functions are implemented. 

Out of six special functions of the C++, the default constructor is automatically generated when ______.

Out of six special functions of the C++, the default constructor is automatically generated when ______.

**(True or False)** A `std::copyable` type is implicitly `std::movable`.

(True or False) A <code>std::copyable</code> type is implicitly <code>std::movable</code>.

**(True or False)** A function parameter with a type modeling `borrowed_range` can be taken by value and an iterator to any of its elements returned from the enclosing function without the danger of a dangling pointer.

(True or False) A function parameter with a type modeling <code>borrowed_range</code> can be taken by value and an iterator to any of its elements returned from the enclosing function without the danger of a dangling pointer.

Let's test your understanding of the concepts in the standard C++ library.
