  • Write comments that explain why the code isn’t obvious just by reading it. Why did you do things the long way? What did you need to work around? Why didn’t you do the thing that anyone reading the code would expect you to do?

    Also write comments that explain the purpose of the functions you use, in case the names of those functions don’t make it clear on their own.



  • FWIW, both big chain grocery stores where I live (in Canada) mark the taxes charged on each item, albeit only with a single-character code that’s explained nearer the bottom of the receipt. I’m surprised that it’s legal anywhere in our respective countries to withhold that information.

    And indeed, even though you can see the nontaxable items clearly on the receipt, that’s not made clear at the shelves where the prices are posted. That’s where they really need to show the price including taxes.

    Some liquor stores in Canada, for example, show both prices: before and after taxes. I’ll let you guess which price is rendered in the smaller font.
