"ocaml_beginners"::[] How to convert a boolean expression to a string

Hi,

I'm newbie for OCaml.
I'm wondering whether there are some built-in function can convert a
string to a boolean exprssion, and convert a boolean expression to a
string.
For instance, convert "s" to a s::bool.
Many Thanks

You can use string_of_bool and bool_of_string:

# bool_of_string "true";;
- : bool = true
# bool_of_string "false";;
- : bool = false
# string_of_bool true;;
- : string = "true"

I don't understand this.
