OKay okay im on it, im gonna sit down and read this, just gonna make some tea...

K cin >> someInteger...and then it goes in you switch statement, switch statements are just like multiple else if statements, the internet will tell you that, true story.

Your program is fine for this stage, actually I would be happy with it if i was a noob.
