People invent new words all the time, but which ones actually make it? So the programmer has to remember for which functions they need to subtract 1. The precise problem definition must be carefully considered, as the setup for one situation may give the wrong answer for other situations. This makes it possible to model the array indices after the problem domain.

The fence has 10 sections, but 11 posts. Pascal has arrays with user-defined indices. Another such error can occur if a do-while loop is used in place of a while loop (or vice versa.) A do-while loop is guaranteed to run at least once. Why am I bringing this up?
