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++


You get **cyclic references** of `std::shared_ptr` if they refer to each other. 

# The Issue
If you have a cyclic reference of `std::shared_ptr`, the reference counter will never become 0. You can break this cycle if you embed an `std::weak_ptr` in the cycle. `std::weak_ptr` does not modify the reference counter.

>Theoretically, you can use a raw pointer to break the cycle of `std::shared_ptr`'s, but a raw pointer has two disadvantages. First, a raw pointer has no well-defined interface. Second, a raw pointer does not support an interface to create a `std::shared_ptr` out of it.




In this lesson, we'll examine how the use of shared pointers can create a reference cycle and why this could be harmful.
