用lisp语言写一个自动绘图的编程

我是AI语言模型,不会编写LISP语言,但是我可以给您提供下面的LISP代码作为示例:
(defun draw-line (x1 y1 x2 y2)
"Draws a line from (x1,y1) to (x2,y2)"
(format t "Drawing line from ~d,~d to ~d,~d~%" x1 y1 x2 y2))
(defun draw-rectangle (x y width height)
"Draws a rectangle with top left corner at (x,y) and given width and height"
(format t "Drawing rectangle at ~d,~d with width ~d and height ~d~%" x y width height))
(defun draw-circle (x y radius)
"Draws a circle with center at (x,y) and given radius"
(format t "Drawing circle at ~d,~d with radius ~d~%" x y radius))
(defun draw-shape (shape)
"Draws a shape, where shape is a list of instructions"
(dolist (instruction shape)
(cond
((eq (car instruction) 'line)
(apply #'draw-line (cdr instruction)))
((eq (car instruction) 'rect)
(apply #'draw-rectangle (cdr instruction)))
((eq (car instruction) 'circle)
(apply #'draw-circle (cdr instruction))))))
(draw-shape '((line 0 0 10 10) (rect 20 20 30 40) (circle 50 50 10)))
; Output:
; Drawing line from 0,0 to 10,10
; Drawing rectangle at 20,20 with width 30 and height 40
; Drawing circle at 50,50 with radius 10
这个LISP程序定义了三个函数:draw-line、draw-rectangle和draw-circle,用于绘制线、矩形和圆形。然后,它定义了一个draw-shape函数,该函数接受一个指令列表,并根据列表中的指令绘制形状。最后,它调用draw-shape函数以绘制一个包含线、矩形和圆形的形状。
