The pitch middle C is C4, which is useful to memorize.
The notes (C, C# or Db, D, D# or Eb, D, F, F# or Gb, G, G# or Ab, A# or Bb, B) are followed by an octave number. For example: C2, F#3, and Bb4. These may also be written in various publications as: C(2), F#(3), Bb(4), C[2], F#[3], Bb[4], or C2, F#3, and Bb4.
The reason the keyboard is designed around the C major scale does not come from piano - it started with the organ. Organ builders discovered long ago that a pipe of 8 feet will give a note close to the pitch called C. This was a convenient place to start
