i have a question about scales that in a scale you must start with the c and end with the other c on the scale

For a scale you start on the root (for example: C in the key of C. F# in the key of F#, Eb in the key of Eb minor, etc) and end on the octave either up or down.

so whats the purose of the other notes thats included in the scale but is not c??

The purpose of the other notes is how they relate to the root and how they relate to each other. These relationships are what make up the sounds of chords and intervals.

can i still use them ??

Yes, you can use any note in the scale (called diatonic) and you can all the notes outside the scale (labeled: non diatonic, chromatic, altered notes). It all depends on what sounds (tones) you want to hear
