By not putting them? What's the problem?

Could you please detail your scenario?

We don't use arrays anymore; we use Lists. But you can use an unsigned datatype as Mehdi said. Or derive your own List that performs a test.

Who "we"? I personally use both and find arrays important... :-)

Solution 1

Define your data type to be unsigned i.e. uint ulong etc.

It would be the best idea, of course, but we just don't know exactly. Maybe an array needs to be populated with some positive values from UI and then the values can be changed. Not likely but possible. It's safer to say that the question makes no sense until it is clarified.

Exactly!
