Say you write a program today. Six months later, your boss asks you to write a similar one. You copy that program, and adjust it.
That's fine, but you have to understand your past code before you can change it.

Wait. Of course you'll understand it. You wrote it.
Maybe not. Your brain doesn't remember all the deets of everything you do. It's common for programmers to not remember how code they're written in the past works.
Most companies have programming standards. Following standards make it easier for future you and others to work with your code.
We'll have a few standards in this course. Not many, just the most important ones. Follow them in every program you hand in.
