To start using C++, you need two things:
A text editor, like Notepad, to write C++ code
A compiler, like GCC, to translate the C++ code into a language that the computer will understand
There are many text editors and compilers to choose from. In this tutorial, we will use an IDE (see below).
An IDE (Integrated Development Environment) is used to edit AND compile the code.
Popular IDE's include Code::Blocks, Eclipse, and Visual Studio. These are all free, and they can be used to both edit and debug C++ code.
We will use Code::Blocks in our tutorial, which we believe is a good place to start.
You can find the latest version of Codeblocks at http://www.codeblocks.org/downloads/26.
Download the mingw-setup.exe file, which will install the text editor with a compiler.
Note: Web-based IDE's can work as well, but functionality is limited.
Let's create our first C++ file.
Open Codeblocks and go to File > New > Empty File.
Write the following C++ code and save the file as myfirstprogram.cpp (File > Save File as)
Don't worry if you don't understand the code above - we will discuss it in detail in later chapters. For now, focus on how to run the code.
In Codeblocks, it should look like this:
When learning C++ at robomag.xyz, you can use our "Submit Example" tool, which shows both the code and the result.
This will make it easier for you to understand every part as we move forward:
