OK, try
(require 'thingatpt)
first.
It is a useful thing even tho your code is
perhaps (?) better in this case.

OK, you can use the C-u prefix to do that.
So `C-c f' is 4^0 = 1,
`C-u C-c f' is 4^1 = 4,
`C-u C-u C-c f' is 4^2 = 16, and so on; and
`C-u x C-c f' is x!
This can be implemented like this:
(require 'cl-macs)
(defun flip-case (times)
(interactive "p")
(cl-dotimes (_ times)
(let ((c (string-to-char (thing-at-point 'char t))))
(delete-char 1)
(cond ((and (>= c ?A) (<= c ?Z)) (insert-char (downcase c)))
((and (>= c ?a) (<= c ?z)) (insert-char (upcase c)))
(t (insert-char c)))) ))
(global-set-key "\C-cf" #'flip-case)
