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

# What’s in the `<ranges>` header?
In the `<ranges>` header, we’ll find concepts that describe the requirements on different types of ranges.

Let’s  suppose that a parameter of a function is a range. But we can assert for any kind of `range`, like `input_range`,` output_range`, `forward_range`, etc.

Let’s have a look at the following range:  `std::ranges::borrowed_range`.

Get an overview of the concepts in the <ranges> header shipped with the C++ standard library.
