Now that you've been introduced to a simple programming language in Python, we need to spend a bit of time talking about a more complex but powerful language called C++. C++ is the original language of Linux, and has been around for many decades, but is still widely used by open source developers. It is similar to Python, but is also a bit different, and since you may need to understand and make changes to C++ code, you should be familiar with it and how it is used.
As with Python, you will need to have access to the language capabilities. These come in the form of a compiler and build system, which turns your text files that contain programs to machine code that the processor can actually execute. To do this, type sudo apt-get install build-essential
. This will install the programs you need to turn your code into executables for the system.
