Question

I need to build a list like: (list (list 1 2) (list 3 4) (list 5 6)) , but there is an error in the following code:

(define example
  (lambda (a b)
    (let ((tmp (+ b 1)))
    (list '(1 b) '(2 tmp) '(3 3)))))

(example 1 4)

The result that I want is (list (list 1 4) (list 3 5) (list 3 3)) but the result I get: (list (list 1 'b) (list 2 'tmp) (list 3 3)) .

Answer 1

You need to do

(list (list 1 b) (list 2 tmp) '(3 3))

or

(list `(1 ,b) `(2 ,tmp) '(3 3))
