At the risk of being blunt, unless one understands what one is
programming, one is in deep trouble. (and, to be fair, the programmer
_is_ asking.) Its not hard to come up with a a program to spin some
numbers. The trick is to have them mean something. As the Bumble Bee.

Yeah Verily. Wisdom in this...

Like much else, its a learning process. Having once (or twice or...)
learnt something, hopefully it IS known. And, hopefully the next
<whatever> comes closer, with less tweaking....
