Feedback and Two Questions about C++


First of all, I LOVE C++!!! It’s a pretty straight forward program so far :slight_smile:

Question 1.
During the Stanford video there was a brief discussion about using “std::” before cout and cin, but its not necessary. However during the reading assignments about Loops in C++, “std::” is utilized. Which is the standard? I would like to keep up with maintaining a consistent best practice.

Question 2.
I am still uncertain on when an “unsigned” loop would be used. Can you please give me some examples?
