With bash, set the glob settings so that missing matches don't trigger an error:

shopt -u failglob # missing matches are just dropped
shopt -s nullglob # missing matches don't report a failure
ls ?c c?

Question-mark is a glob character representing a single character. Since you want two-character filenames, one of them has to be a c, and so it's either the first character or the last character.

With shopt -s dotglob this would also surface a file named .c.

If there are no matching files, setting these shell options causes all of the arguments to be removed, resulting in a bare ls -- listing anything/everything by default.

Use this, instead:

shopt -s nullglob ## drop any missing globs
set -- ?c c? ## populate the $@ array with (any) matches
if [ $# -gt 0 ] ## if there are some, list them
 ls -d "$@"
fi

Try this

ls -d c?

or

ls -d ?c

Use the ? wildcard for file globbing, it represent the number of characters you want to search for. Change c position whether at beginning or at end.

The -d flag will prevent ls displaying the content of subdirectories that match the pattern.
