Let the value of x be 2 in the environment outside theexpression. What is the value of the expression given below?(let ((x 3)(y (+ x 2)))(* x y))
Question
Solution 1
The expression is written in Scheme, a dialect of Lisp. Here's how you evaluate it:
The
let
expression creates a new scope wherex
is bound to3
andy
is bound to(+ x 2)
. In this scope,x
is3
, not2
.The value of
y
is calculated as(+ x 2)
, which is(+ 3 2)
