What is Dijkstra's core idea on programming?
My central idea is that programs are mathematical entities, and their correctness can be established through logical deduction, much like proving theorems. This requires a disciplined approach, breaking down complex problems into smaller, manageable, and provable steps. The goal is not just to make a program work, but to be able to prove its correctness *before* and *after* it is written, eliminating the need for extensive debugging through guesswork.
