Why “do…while” does not exist in F#

Question

I cannot find \"do...while...\"

I have to code like this:

let bubbleSort a=
    let n = Array.length a
    let mutable swapped = true
    let mutable i =         


        

Answer 1

It turns out to be quite easy to write a good enough do-while in F# as a higher-order function:

let doWhile f c =
    f ()
    while c () do
        f ()
