    little sign convention i'm unfamiliar with

    What does the following mean - it was in our sample solutions

    Code:
    while(|-->0)
    {
    
    .... 
    
    }
    I've never come accross it - and forgive me if its far to basic a question to be asking.

    Stick it in a compiler and try it out - should be faster than waiting for someone
    to give you an answer.
    No No's:
    fflush (stdin); gets (); void main ();


    Goodies:
    Example of fgets (); The FAQ, C/C++ Reference


    My Gear:
    OS - Windows XP
    IDE - MS Visual C++ 2008 Express Edition


    ASCII stupid question, get a stupid ANSI

    >while(|-->0)
    My guess is that's a syntax error and would not compile. It probably should be:
    Code:
    while(l-->0)
    Which is the same as:
    Code:
    while( (l--) > 0)
    Or:
    Code:
    while( some_variable--) > 0)

    It's not a syntax error. It's 2 separate operators. decrement followed by greater-than.

    The parentheses to separate the operations are also unnecessary.
    If you understand what you're doing, you're not learning anything.

    yuck @ (l-->0), sometimes white spaces really help.

    In function `main':
    parse error before '|' token

    Thumbs up

    I had to throw it into another editor, because I wasn't sure what it was. If that was indeed in their sample solutions, then somebody goofed.

    No its my bad - i misread it as a '|' instead of an 'l' . Weird thing is theres no l defined anywhere?
    not even a
    Code:
    int l-->0
    ...oh well.

    edit: - Problem fixed

    The code states the following :

    Code:
    //adds number of spaces.
    void(char ch, int nlength)
    {
      while(nLength-->0)
          putchar(ch);
    }
    Its code like this that makes me turn to C programming board! I would normally use a for loop and loop nLength times - but here the instructor starts with nLength and sets it to decrement till 0.

    Also theres another loop where he passed an l to the function - i missed it.
