To run examples from this book, you will need a computer running Windows, Linux, or macOS (C++ programs can be built on something as small as a Raspberry Pi). You will also need a modern C++ compiler, such as GCC, Clang, Visual Studio, or another compiler that supports the C++ language up to C++17. You will need a basic knowledge of GitHub and Git in order to clone a project with examples.
