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);`
