This creates a fixed-sized array of length `len` (using the deprecated syntax). Since the length is part of the type, it needs to be known at compile time.
You probably want a dynamic array instead. `auto output = new float[len]`
Also note that you're not seeding your random number generator, so it will produce the same sequence every time. You probably want `auto gen = Random(unpredictableSeed);`
