[Docs]: Expand on the "Getting Started with CPP" post

[iamanolive]

The getting started with CPP post (link: https://subhadipbhowmik.github.io/30-Days-Of-CPP/docs/day-01/getting-started-with-cpp) currently only contains a minimal outline of everything the post is supposed to include, and i'd like to expand it into a full-fledged tutorial.
