Help translate c+ => lisp!?

[georg]

Hi,

I am a newcomer can anywhere translate this to lisp?

cin<<x;

for( i = 0; i < x; i++) {
…
}

Thx..

Adding in types, the C++ is probably

Code: Select all

int x;
cin >> x;
for(int i=0; i<x; i++) { ... }

Here's roughly equivalent CL.

Code: Select all

(let ((x (read *standard-input*)))
  (assert (integerp x))
  (dotimes (i x) ...))

There a few options for checking that x is an integer (such as an IF instead of the assert), there are times to prefer DO or LOOP over DOTIMES, and *STANDARD-INPUT* is a default and doesn't need to be specified to READ.
Please check out some of the books in the FAQ for this forum.

Thx for you reply!

still I have a problem whit the ACAD lisp

me lisp doesn't not work...

(print)

(defun C:PL ()
(setvar "OSMODE" 1)
(INITGET 1)
(setq P1 (getpoint "\n Lower Left Endpoint: "))
(INITGET 1)
(setq P2 (getpoint "\n Upper Right Endpoint: "))
(setvar "OSMODE" 0)
;;***********************************************

(print "How many copies?")

(let ((x (read *standard-input*)))
(assert (integerp x))
(dotimes (i x)
;************************************************* **************************************************
(setvar "cmdecho" 0)
(command "-PLOT" "j" "" "Canon MP270 series Printer" "A4" "" "" "" "fe" P1 P2 "" "" "" "acad.ctb" "" "" "" "" "" "" "")
))

Are we talking Common Lisp or Autolisp (used by AutoCad) or something else?
What program reads the files?

The prog. is for Acad! Is there a difference?

Well, it is another Lisp dialect, so I presume there is.
