The Weird and The Wonderful

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

Beh, any real programmer would write it like this:

int primes[] = {2,3,5,...133};
const int* end = primes + sizeof(primes)/sizeof(int);
return (std::find(primes, end, num) != end);

And any real engineer would build something like this: Big Grin | :-D

bool IsPrime(int i)
{
  if (i<2)
    return false;
  if (i == 2)
    return true;
  if (i%2 == 1)
    // All odd numbers are prime:
    // 3 ... prime
    // 5 ... prime
    // 7 ... prime
    // 9 ... measuring fault
    // 11... prime
    // 13... prime
    // and so on...
    return true;
  else
    return false;
}

Ah, but in .net (C#) we can use a (generic) dictionary and an enum to further extend the required functionality...

public static partial class NumberKeeper
{
    [System.FlagsAttribute]
    public enum NumberProperty
    {
        None       =   0
    ,
        Odd        =   1
    ,
        Even       =   2
    ,
        Positive   =   4
    ,
        Negative   =   8
    ,
        Prime      =  16
    ,
        PowerOfTwo =  32
    ,
        Square     =  64
    ,
        Cube       = 128
    ,
        Fibonacci  = 256
    ,
        Factorial  = 512

        /* et cetera */
    } ;

    public static readonly System.Collections.Generic.Dictionary<int,NumberProperty> Numbers ;

    static NumberKeeper
    (
    )
    {
        Numbers = new System.Collections.Generic.Dictionary<int,NumberProperty>() ;

        Numbers.Add (   0 , NumberProperty.None ) ;
        Numbers.Add (   1 , NumberProperty.Odd  | NumberProperty.Positive                         | NumberProperty.PowerOfTwo | NumberProperty.Fibonacci | NumberProperty.Factorial ) ;
        Numbers.Add (   2 , NumberProperty.Even | NumberProperty.Positive | NumberProperty.Prime  | NumberProperty.PowerOfTwo | NumberProperty.Fibonacci | NumberProperty.Factorial ) ;
        Numbers.Add (   3 , NumberProperty.Odd  | NumberProperty.Positive | NumberProperty.Prime                              | NumberProperty.Fibonacci ) ;
        Numbers.Add (   4 , NumberProperty.Even | NumberProperty.Positive | NumberProperty.Square | NumberProperty.PowerOfTwo ) ;
        Numbers.Add (   5 , NumberProperty.Odd  | NumberProperty.Positive | NumberProperty.Prime                              | NumberProperty.Fibonacci ) ;
        Numbers.Add (   6 , NumberProperty.Even | NumberProperty.Positive                                                                                | NumberProperty.Factorial ) ;
        Numbers.Add (   7 , NumberProperty.Odd  | NumberProperty.Positive | NumberProperty.Prime  ) ;
        Numbers.Add (   8 , NumberProperty.Even | NumberProperty.Positive | NumberProperty.Cube   | NumberProperty.PowerOfTwo | NumberProperty.Fibonacci ) ;
        Numbers.Add (   9 , NumberProperty.Odd  | NumberProperty.Positive | NumberProperty.Square ) ;
        Numbers.Add (  10 , NumberProperty.Even | NumberProperty.Positive ) ;
        Numbers.Add (  -1 , NumberProperty.Odd  | NumberProperty.Negative ) ;
        Numbers.Add (  -2 , NumberProperty.Even | NumberProperty.Negative ) ;
        Numbers.Add (  -3 , NumberProperty.Odd  | NumberProperty.Negative ) ;
        Numbers.Add (  -4 , NumberProperty.Even | NumberProperty.Negative ) ;
        Numbers.Add (  -5 , NumberProperty.Odd  | NumberProperty.Negative ) ;
        Numbers.Add (  -6 , NumberProperty.Even | NumberProperty.Negative ) ;
        Numbers.Add (  -7 , NumberProperty.Odd  | NumberProperty.Negative ) ;
        Numbers.Add (  -8 , NumberProperty.Even | NumberProperty.Negative | NumberProperty.Cube   ) ;
        Numbers.Add (  -9 , NumberProperty.Odd  | NumberProperty.Negative ) ;
        Numbers.Add ( -10 , NumberProperty.Even | NumberProperty.Negative ) ;

        /* et cetera */

        return ;
    }

    private static bool
    HasProperty
    (
        int            Subject
    ,
        NumberProperty Property
    )
    {
        return ( Numbers.ContainsKey ( Subject ) && ( ( Numbers [ Subject ] & Property ) == Property ) ) ;
    }

    public static bool
    IsPrime
    (
        int Subject
    )
    {
        return ( HasProperty ( Subject , NumberProperty.Prime ) ) ;
    }

    /* et cetera */

}

(I'd also add XML serialization of the list.)

Which begs the question: "Sophisticated or sophomoric?"

I used the while loop and global variable to wait for thread to finish. Laugh | :laugh:

I always recall it when ever I write WaitForSingleObject after that. Big Grin | :-D

DWORD dwStart = GetTickCount();<br />

while( m_sManagerNode.IsEmpty() == FALSE ){<br />
	if( GetTickCount() - dwStart >= 60000 ){<br />
			bReturn = FALSE; <br />

I think it already happened to everyone to rewrite existing code or API just because one did not know that the code already existed.
In a different manner, as I was a student, it took me one week to transform serial signals (-12/+12 Volts) into a (0/+5V) signals using all kind of electronic beings (resistance, amplifier, ...) just to find out after that that someone had already thought about the problem and that we could buy RS232 integrated circuits everywhere.
