While loop

New to Julia

Hello, I’m trying to rewrite some old java code to julia and I’ve problem with whlie loop. In java I was while(++a < b && c>d) and here I see that ++ is “not a unuary operator”. Is it possible to create this kind of compound loop in Julia?

julia> a=1

julia> while (a=a+1) < 3
       println(a)
       end

Or, for a more complete example:

function test()
    a = 0
    b = 5
    c = 10
    d = 1
    while (a += 1) < b && c > d
        c -= 1
        @show (a, b, c, d)
    end
end

I think it looks better (and more similar to Java) with

a += 1

here.

Fixed. I initially tried with a += 1 but it failed, now I see it was just because I forgot the parenthesis around the assignment when I used the += operator (and automatically wrote them when changed the expanded form).
