Did the original formatting cause an issue for you? If so, what was it and what compiler and platform (windows, linux) are you using?

[Zeffar]

While the original formatting didn't cause any issues when compiling it, I couldn't help but notice the coding style was inconsistent. This PR does not aim at fixing bugs, as much as it aims at keeping a consistent format throughout the code. Before adding new features, it is important for the code to be readable and have the same coding style all throughout.
