  • How to prevent regex from stopping at the first match of alternatives ?

    - by miket2e
    If I have the string hello world , how can I modify the regex world|wo|w so that it will match all of "world", "wo" and "w" rather than just the single first match of "world" that it comes to ? If this is not possible directly, is there a good workaround ? I'm using C# if it makes a difference: Regex testRegex = new Regex("world|wo|w"); MatchCollection theMatches = testRegex.Matches("hello world"); foreach (Match thisMatch in theMatches) { ... }

  • Should i use a C function or Obj-C Method?

    - by Daniel Granger
    I'm about to create a function which adds to NSDateComponents together is there any advantage to putting this in a C style function or should it go in a Obj-C method? Is there ever a reason to use one rather then the other or should I always stick to Obj-C? BTW: Not that it makes any difference I'm sure but this is for an app on the iPhone Many thanks

  • if `int != 1` or `int == 0`?

    - by Emil
    Hey. I was coding here the other day, writing a couple of if statements with ints that are always either zero or one (~bools), and I asked myself: Should I use if (int == 1) or if (int != 0) ? Is there any difference at all? Please, don't answer with stuff regarding the int may being more/less than 1/0, that's not what I want to know.
