geting the median of 3 values using sheme car & cdr
- by kristian Roger
Hi still stuck with the ugly scheme
the problem this time is to get the median of three values (easy)
I did all these :
(define (med x y z) (car(cdr(x y z)))
and it was accepted but when testing it
(med 3 4 5)
I will get this error
Error: attempt to call a non-procedure
(2 3 4)
and when entering letters inetead of number i got
(md x y z)
Error: undefined varia
y
(package user)
using somthin else than x y z i got
(md d l m)
Error: undefined variable
d
(package user)
so what is wronge ?!
