To begin developing in C++ you should download and install an Integrated Development Environment (IDE) that supports C++. A good choice is Microsoft's own Visual Studio. If you do not have Visual Studio but would like to try out the examples in this book in a similar environment you can download Visual Studio Express from Microsoft's website. This is a lightweight version of Visual Studio that is available for free. Alternatively, you can develop using a simple text editor – such as Notepad – although this is less convenient than using an IDE. If you choose to do so, just create an empty document with a .cpp file extension and open it in the editor of your choice.
