To be a little clearer, a string is defined to be a sequence
of characters, so every element of a string is a character.
So the idera of checking to see if a string contains only
characters is meaningless. If you are asking how to
distinguish digits from letters, then that is done by
simple tests, and you really should be able to figure this
out for yourself.

Exceptions are most certainly irrelevant. I suspect you are
flailing around at random here, you really need to make more
of an effort to understand what you are doing. I would suggest
working your way carefully and completely through one of the
online tutorials at www.adapower.com, or really reading through
your text book carefully.

You may be able to bash a small program into working without
understanding what you are doing, but this definitely will
not scale to real programs!
