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++

The initialization of variables was uniform in C++11. 

# Two Forms of Initialization 

> **Rule:** A {}-Initialization is always applicable.

## Direct Initialization
```c++
string str{"my String"};
```
## Copy Initialisation
```c++
string str = {"my String"};
```


# Preventing Narrowing
The initialization with `{}` prohibits narrowing conversion. 

Narrowing, or more precisely narrowing conversion is an implicit conversion of arithmetic values. This can lead to a less accurate result which is extremely dangerous.

The following example outlines the issue with the classical initialization for fundamental types.  It doesn’t matter whether we use direct initialization or assignment.


In this lesson, we will learn about initialization with {} and how it prevents narrowing.
