    Contest Sign-Up, Regular Expressions.

    This is a relatively easy contest, so i'm only going to have it running for one week. All entries will be submitted to my email address (ebrooks@hfx.eastlink.ca) before 12:00AM (your time) on April 1st.
    Please play fair and don't search google or ask others for help on this; I know this is all over the internet.

    Your regular expression string matching functions will take the prototypes:
    Code:
    bool wildcmp(const TCHAR*, const TCHAR*); // Case sensitive
    bool wildicmp(const TCHAR*, const TCHAR*); // Case insensitive
    or equivalent (eg. bool wildcmp(const tstring&, const tstring&); ) As long as it satisfies the following expression: wildcmp(TEXT("*"), TEXT("Hello"));

    Both functions will work with either unicode or ASCII strings. Whether unicode strings are passed to your function depends on whether or not _UNICODE is #defined.
    The only wildcard operators you need to handle in your functions are '*' and '?'. Return true on success, and false on failure.

    I will participate. I just got an idea on how it can be done really elegantly.

    Perhaps you could explain what the functions are suppose to do. Instead of assuming every one that wants to play knows what Regular Expressions are, and what this function has to do with them.







    I know. I'm stupid.

    Can you be a little more specific? I mean this: "The only wildcard operators you need to handle in your functions are '*' and '?'. " isn't very helpful to know what our functions are supposed to do. Are those the ONLY things its supposed to do? How about [a-z], etc?

    May you please make a list of what needs to be in?

    If you don't know what a regular expression is, look it up on google.

    These would all evaluate true:
    wildcmp(TEXT("H?l*"), TEXT("Hello"));
    wildcmp(TEXT("*"), TEXT("Hello World"));
    wildcmp(TEXT("R?gul* E??r*ns"), TEXT("Regular Expressions"));

    The two wildcard "operators" you must account for in your functions are '?' (where any single character is wild) and '*' (where any number of characters can be wild)

    This is a contest geared towards beginner programmers, although I encourage everyone to sign up.

    OK, got it. Just those two things and nothing else.

    I'll try to see if I can fit some time into this. But I still have to research regular expressions. So, probably not, but I'll try, so do not count me in yet.

    The functions compares two strings and returns true if and only if they are equal.

    The ? can match any single character.
    The * can match zero or more characters.

    Question: What should this evaluate to? I have it evaluating to false.

    i*ko
    iskasko

    format:
    -pattern
    -text

    That should evaluate true, since the asterix can be replaced by any number of characters.

    i[skas]ko == iskasko
