WebThe first part of the response from OCaml, val x : int ref, indicates that x is a variable whose type is int ref. We have a new type constructor here. Much like list and option are type constructors, so is ref. A t ref, for any type t, is a reference to a memory location that is guaranteed to contain a value of type t. WebType bool: Booleans. The boolean values are written true and false . The usual short-circuit conjunction && and disjunction operators are available. Type char: Characters. Characters are written with single quotes, such as 'a', 'b', and 'c'. They are represented as bytes —that is, 8-bit integers— in the ISO 8859-1 “Latin-1” encoding.
