Expert Solution & Answer
Chapter 5, Problem 20RQ
Explanation of Solution
let construct in F#:
In F# the let construct’s form is.
let left_side = expression
Here, left_side may be name or any tuple pattern. The scope of name declared inside the function is from the end of declared expression to the end of the function.
Example:
let x =
let y = 1
let z = y+2
z;;
let a = z+x;;
Here in example scope of x is all over the code, but scope of y and z is till the indentation. Line of let x is value bounded to x and can be any expression...
