Between B and C and between E and F there is just a half step - no room there for a black key. ... Since there's no black key between B and C you'll be playing that B# on the same piano key used for C, but that's part of the compromise that makes the piano workable.

Why is there no half step between B and C?
The reason why it's only a half step is because there technically isn't a “B#” or “Cb.” A half step denotes moving from one tone (say A natural) to the next full tone (B natural). And since there is no middle from B to C, it's only a half step.
Is there a semitone between B and C?
There is no note between B & C. By dividing a pitch, by 1.05946309436, you get the next lower semitone. There is a B#, which is enharmonic to C.
How many steps do you take between notes?
Notes that are directly next to each other—such as E and F, or A sharp and B—are a half step apart. Two half steps equal one whole step. The notes G and A are one whole step apart, as are the notes B flat and C.
