Got it. In addition, the black notes in between are sharps/flats.

IE. The black note between C and D is C Sharp/D Flat

Though I doubt this will ever apply to you, it may still be worth noting. Notice that between B and C there is no black key, but sometimes you'll still see someone refer to something like "B Sharp". B Sharp is just C (a sharp means to just go up a semitone, flat means to go down a semitone.) You also might see something called a double-sharp, which just means to go up a full tone (C double-sharp is D). Again, these are details you will probably never encounter, but good to know just in case.
