Embedded Programming with Modern C++  is highly valuable for each professional programmer.

In the past, embedded and system programming have had their pitfalls, but modern C++ has been designed to be a better language for this type of development, addressing the previous pitfalls/requirements explicitly. What are these requirements? Embedded systems deal with safety-critical systems, meaning they must guarantee high performance combined with limited resources, while also working in parallel.

The scope of this course goes beyond just embedded programming. Developers who write servers, games, or trading systems may especially benefit from this course because they also have to deal with safety-critical systems, high performance, reduced resources, and parallel execution in their jobs.

To get the most out of the course, you only need a basic understanding of C++. Building off this understanding, this course goes over all the essentials of embedded programming with Modern C++.

Let's get started!

Embedded Programming with Modern C++

`static_assert` is the tool in modern C++ used to make our code safe.

# static_assert

The usage of `static_assert` is quite easy. `static_assert` requires an expression and a string. The expression must be predicate that can be evaluated at compile time. Predicate means the expression returns `true` or `false`. If the expression evaluates to `false`, we will get an error message at compile-time with the string as a message. Of course, we get no executable.

There are a few points we must consider.

* The `static_assert` expression will be evaluated at compile-time, and we have no runtime overhead.

* Expressions that can be evaluated at compile time are called constant expressions. 

* We can use `static_assert` expressions in all parts of our program. Therefore, it is a good idea to put general requirements on our source code in a separate header. As a result, the `static_assert` expression will be automatically verified at compile time if we include the header. This helps to port our code to a new platform since we can easily check if the new platform supports the type requirements.

In this lesson, we will learn about assertions at compile time in modern C++.
