As it is, it should accept strings as long as the user of the program types
double-quotes around his input, e.g. "my input". A sequence of characters
will be returned from the input() function.

If you don't want to force the user to use quotes, then you
will have to use gets(0) to read the typed input as a string.
Then, if the input string contains digit characters you can
convert from string form to numeric form, by using value(),
or one of the similar routines that Jacques posted a few days ago.
