If this is for a homework assignment, shouldn't you be figuring out
the solution on your own?  I will give you a pointer: What you wish
to do is called "string concatenation", and there is a function in
the standard library that handles it. (Actually, there are two
functions in the standard library that would work here. I leave
finding them to you.)

Hi Dane,

 I din't get your original post, but if understand the above correctly, your
exercise looks much like an exercise I once had to explain to some students.
As to your question regarding "appending" (and to some rather misleading
replies you got to it): yes, you can append the "for value" to a variable
name, but the result would be a string, and not a variable name you could
use to access variable values.
I would say that the solution your teachers want to see would use either a
"switch" statement or, if you havn't learned switchs yet, six "if"
statements. Either way its not very pretty, but then again its supposed to
teach you something, not to be pretty ;)

Another hint: if you have to iterate more then 6 times in your for-loop you
might want to consider using the modulo operator "%".

 Hope that helped a bit

 Lior

Hmm...three of us have responded now, and we all
seem to have interpreted your question differently.

Do any of our responses seem to fit what you were
looking for? If not, could you please rephrase
and/or elaborate upon the question?
