I am trying to make a script that takes a word and each letter up and turns it into a separate variable. My code currently does not work but I feel I just need to tweak one thing that I am unsure of.
(ex: if forum was typed in letter1=f; letter2=o; letter3=r;...)
Thank you

iswdigit
ISWDIGIT(3) Linux Programmer's Manual ISWDIGIT(3) NAME
iswdigit - test for decimal digit wide character SYNOPSIS
#include <wctype.h> int iswdigit(wint_t wc); DESCRIPTION
The iswdigit() function is the wide-character equivalent of the isdigit(3) function. It tests whether wc is a wide character belonging to the wide-character class "digit". The wide-character class "digit" is a subclass of the wide-character class "xdigit", and therefore also a subclass of the wide-character class "alnum", of the wide-character class "graph" and of the wide-character class "print". Being a subclass of the wide character class "print", the wide-character class "digit" is disjoint from the wide-character class "cntrl". Being a subclass of the wide-character class "graph", the wide-character class "digit" is disjoint from the wide-character class "space" and its subclass "blank". Being a subclass of the wide-character class "alnum", the wide-character class "digit" is disjoint from the wide-character class "punct". The wide-character class "digit" is disjoint from the wide-character class "alpha" and therefore also disjoint from its subclasses "lower", "upper". The wide-character class "digit" always contains exactly the digits '0' to '9'. RETURN VALUE
The iswdigit() function returns nonzero if wc is a wide character belonging to the wide-character class "digit". Otherwise, it returns zero. ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7). +-----------+---------------+----------------+ |Interface | Attribute | Value | +-----------+---------------+----------------+ |iswdigit() | Thread safety | MT-Safe locale | +-----------+---------------+----------------+ CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C99. NOTES
The behavior of iswdigit() depends on the LC_CTYPE category of the current locale. SEE ALSO
