    Im gonna go with, theres no 'else' so wouldn't it do the launchmissles() no matter what?
  5. goldfish

    goldfish Lt. Sushi.DC

    Nope ;)

    spelling means nothing, and I'm english so i spell it authorisation

    spaces between authorisation and = sign??
  7. goldfish

    goldfish Lt. Sushi.DC

    nope, but closer ;)

    no 'then' so the launchmissles() would be separate from the 'if'.

    not sure seeing as how i don't know c

    jarcher I can't handle a title

    I don't know a thing about programing, or spelling for that matter
    but i would say that
    authorisation= launchmissles

    The Brackets? I seem to remember those brackets hiding text in Pascal, but that was 15 years ago, and I haven't done any programming since. Never did C.

    im gonna go with you, now that i think about it. WHen I did c++, I never used parenthesis. Heck, neither in basic too.

    That would be the curly brackets around launchmissles();

    Hmmm. Now that I think back, maybe it was * * that hid text.

    Maybe the ";" is in the wrong place, not being on the end of the line(after the last bracket).

    Maybe I'm rambling...

    if (authorisation = "yes") {(launchmissiles)};

    Makes more sense to me. Then again, I'm not a programmer. :rolleyes:

    nope, launchmissiles() is a perfectly normal bit of code.

    You're not gunna get it, unless Kodo comes along all of a sudden :p


    its the authorisaton="yes" part. when you are comparing two values, you use ==, !=, >, < .... the = charachter signifies the operation of setting a variable. That condition says that if (set authorisation to yes) works correctly, then... So, prodvided the variable can be set, it will always return true, regardless of what authorisation was to start with.

    () is going to launch missiles regardless?

  17. goldfish

    No, (authorisation = yes) makes authorisation equal to yes, rather than checking if it equals yes or not. To check it, it needs to be if (authorisation == yes).

    ahhh, in C++ I used to spend hours trying to figure out what I was going wrong, turned out to be just that.

    I'm learning a bit of PHP and this seems like it would catch quite a few people. So whats wrong with this one?

    $blah = "Hello";
    print ('$blah and Welcome');

    Goldfish, stay outta this one!

    You don't use print in PHP. You use echo...or at least I think so. And, you don't need to put the variable in the (). This is how I think it should be:

    $blah = "Hello";
    echo $blah (' and Welcome');
