Single Class or Several Small Classes?

[KodeKrazy]

I would like to get the opinions of the members of this forum on whether you think it is better to write a single class with all the functions, declarations, etc. or do you consider it better form to group similar functions/subs into smaller classes? Why? What are the advantages/disadvantages of both methods?

I always work with different classes, they're not that small, but they group similar functions. i.e.

I usually have all the public declarations in only one, but the procedures are well grouped; If working on a calculator, i'd use a Calculus, Trigonometrics, Basics, etc.

Each one with 10 to 15 procs.

Its easier to find things and to keep it all organized. But i think it depends on how it works for each one.
