Problem Statement

If your system has a means to generate random numbers involving not only a software algorithm   (like the /dev/urandom devices in Unix),   then: show how to obtain a random 32-bit number from that mechanism.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Random number generator (device) step by step in the Icon and Unicon programming language

Source code in the icon programming language

procedure main(A)
    n := integer(A[1])|5
    every !n do write(rand(4))
end

procedure rand(n)
    f := open("/dev/urandom") | stop("Cannot get to urandom!")
    x := 0
    every !n do x := x*256 + ord(reads(f,1))
    close(f)
    return x
end
