1) Consider the following Scheme definition:
>> (define (test x y) (if (= x 3) 1 y))
Write the output of the following call to this function
>> (test 3 (/ 5 0))
a) assuming normal-order evaluation is used (5 pts):
1
b) assuming applicative-order evaluation is used (5 pts):
Error: Division by zero!
2) Write the output of the following programs:
a) >> (let ((a 3) (b 4))
(let ((a 5) (b a))
(let ((a b) (c a))
(+ a b c)) ) )
Output (5 pts):
11 ;(3+3+5)
b) >> (let ((a 3) (b 4))
(let* ((a 5) (b a))
(let* ((a b) (c a))
(+ a b c)) ) )
Output (5 pts):
15 ;(5+5+5)
