Same goes for B and C. B sharp doesn't exist nor does C flat.

This is because a flat or a sharp officialy is between two notes. But since there are no notes between either B and C or E and F you can't call it by that name.

Actually....there is such a thing as Fb or E#, etc. Depending on the key you are in, you would have to use certain notes. Otherwise you won't be able to correctly fill out a scale.

Take a look at the Fb major scale.
Fb, Gb, Ab, Bbb, Cb, Db, Eb and Fb

You have to call it an Fb or else you would be repeating E with an Eb then another E.
