Should I use unsigned integers for counting members?

Question

Should I use unsigned integers for my count class members?

Answer

For example, assume a class

TList  = class

Answer 1

Boundary conditions frequently present problems. Allowing for a type that can go negative may just shift the issue. Perhaps it shifts it in a way that's easier to debug, perhaps not. I started off using integers for counting loops like that, but later on switched to cardinals to help me catch errors.
