Can someone expand on the syntax for symbols? I can develop the check-guess
game simply without symbols but cannot with symbols.
Trying many versions of the symbol syntax but with no success.
This the example for symbols, but how can I test conditions with a symbol?
(define (reply s)
(cond
[(symbol=? s 'GoodMorning) 'Hi]
[(symbol=? s 'HowAreYou?) 'Fine]
[(symbol=? s 'GoodAfternoon) 'INeedANap]
[(symbol=? s 'GoodEvening) 'BoyAmITired]))
;function check-guess
;given number evaluate to one of three answers
;number -> number -> string
tested without symbols and got it working so was trying to emulate this with
symbols
(define (check-guess guess target)
(cond
[(< guess target) "Too Small"]
[(= guess target) "Perfect"]
[(> guess target) "Too large"]
;(define (check-guess guess target)
; (cond
; [(symbol=? 'guess (< guess target) 'Too small)]
; [(symbol=? 'guess (= guess target) 'Perfect)]
; [(symbol=? 'guess (> guess target) 'Too Large)]))
;(define (check-guess guess target)
; (cond
; [(symbol=? (< guess target) 'True 'Too Small)]
; [(symbol=? (= guess target) 'True 'Perfect)]
; [(symbol=? (> guess target) 'True 'Too Large)]))
;(define (check-guess guess target)
; (= s( < guess target))
; (= s( = guess target))
; (= s( > guess target))
; (cond
; [(symbol= s 'true 'Too Small)]
; [(symbol= s 'true 'Perfect)]
; [(symbol= s 'true 'Too Large)]))
;(define (check-guess guess target)
; [(symbol=? guess (< target guess) "Too small")]
