Join me in these bi-weekly series to explore the topic of error reporting in C++.
The focus of this course is the design of functions that normally return a value, but an error may occur so, what should they return instead?

In this video we will be looking at returning an `std::expected` type of an error code and the contents of the file.
`std::expected` is a type that was added to the standard library as of C++23 and is essentially a specialization of a `variant`.
This approach allows us to distinguish between different errors, protect the contents of the file against accidental access and has some cool functional features that can make it a very powerful tool.

The course is also available FOR FREE on Udemy.
It includes coding exercises so you can practice what you have learned.
