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++

A **variadic template** is a template with an arbitrary number of parameters.

```c++
template <typename ... Args>
void variadicTemplate(Args ... args){ . . . . }
```

# Parameter pack
* By using the ellipse (...) `Args-` or `args` becomes a parameter pack
* `Args` is a template parameter pack, and `args` is a function parameter pack
* Parameter packs can only be packed or unpacked
* If the ellipse is left from `Args`, the parameter pack will be packed. If the ellipse is right from Arge, the parameter pack will be unpacked.

>The compiler can automatically deduce the template arguments.

Variadic Templates are often used in the Standard Template Library:
* `sizeof-Operator`, `std::tuple`, `std::thread`


The usage of parameter packs obeys a typical pattern.
* Perform an operation on the first element of the parameter pack and recursively invoke the operation on the remaining elements.
 * The recursion ends after a finite number of steps.
* The boundary condition is typically a fully specialized template.

In this lesson, we will learn about one of the powerful new tools of C++11: variadic templates.
