Why Array Indices Should Start at Zero

2025-03-21

This essay argues why array indices in computer science should begin at zero, not one. Through mathematical reasoning and examples from programming languages, the author demonstrates the superiority of zero-based indexing: it's more mathematically consistent, avoids ambiguous boundary conditions, and leads to cleaner, more efficient code. The piece also touches upon historical inconsistencies in programming language index choices and their resulting inconveniences.
