i think it's
for((initialze vars); (while statement here TRUE); (modify vars))
{
/*something*/
}
in your case c==9 is initially false (you set c=0), so your for loop
will not execute and c will not be modified.

this should work fine because c will not be incremented past 9

any function (even main) which returns a value (!void) should have a
return statement i think, and might not need the exit statement unless you
are stopping the program abnormally.

Instant C++ was my favorite, but it falls along the definition of a
tutorial, although i used it for reference. Text books are sometimes good
for reference since they don't walk you through things as much. Try your
local university book store and see what the students are using. IMHO.
