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++

# Example - RAII

RAII stands for **R**esource **A**cquisition **I**s **I**nitialization, and it is one of the most important idioms in C++. It states that a resource should be acquired in the constructor of the object and released in the destructor of the object. It is important to remember that the destructor will automatically be called if the object goes out of scope.

Is this not deterministic? In Java or Python (`__del__`), you have a destructor but not the guarantee. Therefore, if you use the destructor to release a critical resource, such as a lock, it can end disastrously. In C++, however, this problem is prevented. 

Look at the example below:

The example in this lesson shows the deterministic behavior of RAII in C++.
