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++

# Memory Deallocation
## delete
A `new` with previously allocated memory will be deallocated with `delete`.

```c++
Circle* c= new Circle;
...
delete c;
```
The destructors of the object and the destructors of all base classes will be automatically called. If the destructor of the base class is virtual, we can destroy the object with a pointer or reference to the base class.

After the memory of the object is deallocated, the access to the object is undefined. We must initialize the pointer of the object to a point it to a different object.

In this lesson, we will learn about the second subsection of memory management - memory deallocation.
