How do I get the type of a value in Scheme?

Question

I want a function that gets the type of a value at runtime. Example use:

(get-type a)

where a has been defined t

Answer 1

To check the type of something just add a question mark after the type, for example to check if x is a number:

(define get-Type
  (lambda (x)
    (cond ((number? x) "Number")
          ((pair? x) "Pair")
          ((string? x) "String")
          ((list? x) "List")))) 

Just continue with that.
