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.

WebThe second part of the response shows us the contents of the memory location. Indeed, the contents have been initialized to `0`. The second phrase, `!x`, dereferences `x` and returns the contents of the memory location. Note that `!` is the dereference operator in OCaml, not Boolean negation. The third phrase, `x := 1`, is an assignment. WebOCaml has built-in printing functions for a few of the built-in primitive types: print_char, print_string, print_int, and print_float. There’s also a print_endline function, which is like …
