To compile and run the examples in this chapter, you must have administrative access to a computer running Ubuntu 19.04 with a functional internet connection. Note that the rest of this book uses Ubuntu 18.04. Since we will be discussing C++20, which is still in development, we need the latest and greatest versions of GCC in this specific chapter. Before running these examples, you must install the following:

> sudo apt-get install build-essential git cmake

If this is installed on any operating system other than Ubuntu 18.04, then GCC 7.4 or higher and CMake 3.6 or higher will be required.
