Solution
1. C-double-sharp note
C## is a white key on the piano.
Another name for C## is D, which has the same note pitch / sound, which means that the two note names are enharmonic to each other.
It is called double-sharp because it is 2 half-tone(s) / semitone(s) up from the white note after which is is named - note C.
Middle C (midi note 60) is shown with an orange line under the 2nd note on the piano diagram.
These note names are shown below on the treble clef followed by the bass clef.

Lesson steps
1. Piano key note names
The white keys are named using the alphabetic letters A, B, C, D, E, F, and G, which is a pattern that repeats up the piano keyboard.
Every white or black key could have a flat(b) or sharp(#) accidental name, depending on how that note is used. In a later step, if sharp or flat notes are used, the exact accidental names will be chosen.
The audio files below play every note shown on the piano above, so middle C (marked with an orange line at the bottom) is the 2nd note heard.

2. C-double-sharp note
C## is a white key on the piano.
Another name for C## is D, which has the same note pitch / sound, which means that the two note names are enharmonic to each other.
It is called double-sharp because it is 2 half-tone(s) / semitone(s) up from the white note after which is is named - note C.
The next note up from C## is D# / Eb.
Or put another way, D# / Eb is 1 half-tone / semitone higher than C##.
The next note down from C## is C# / Db.
Or put another way, C# / Db is 1 half-tone / semitone lower than C##.
