hi. This is so great article and i appreciate you have written it very well…Well i am still scratching my head figuring out the final complex parse tree, but the concept of operator precedence is very well understood..thanks a ton..

@Nate Cavanaugh – thanks for the kind words! One thing which I find annoying about other websites and documents about parse trees and related things is that they’re aimed at academics and hardcore programmers rather than the rest of us. I think that it’s important to understand that subtleties of language constructs (such as the difference between ++i and i++) which again is something that is all too often overlooked in my opinion.

Even as someone who understood operator precedence, I have to give you a ton of credit. The visual laying out of the parse trees as well as the extra time you took in explaining each operation, and breaking the article into easily consumable chunks made this a pleasure to read.
Thanks for posting it :)
