Question about structure

Hi, I have a question about scheme structure.

So I use define-struct to create this structure.

say (define-struct fruit (color shape))

now I want to write a function which consumes 2 fruit values and compare their color and shape.

I can write a cond to compare, the problem is I don't know how to define the 2 fruit values. In example I saw, if I use (make-fruit...) I have to type in actual variables in (in this case color shape). but I want those to be input after I run the function. How do I define the 2 fruit values?

RE: Question about structure

You can try

CODE --> scheme

(define-struct fruit (color shape)) (define (make-a-fruit) (let ((color (read-color)) (shape (read-shape))) (make-fruit color shape))) (define (read-color) (print "what color ? ") (read)) (define (read-shape) (print "what shape ? ") (read))
