It isn't Friday but how about a code quest anyway

Ennis Ray Lynch Jr

I want to see do loops that are not pre-initialized and do not rely on looping on and that do not rely on a true in the while condition? Why do I want to see it? Well, do loops are cool but not if you have to have the same line of code twice. Can you author a do loop that is not initialized outside of the block, does actual work, and needs a loop? (Remember, functions and methods like getDate() or DateTime.Now can't be used because they have to be initialized somehwere)

:) Actually, the homework version of the question is trivial, converting a while loop to a do loop or the reverse (ok, I thought it was trivial until I was a T.A. and graded what kids turned in), I think my question is non-trivial enough to be a fun challenge.

I don't know about that, but I quite often have do-loops because I can often guarantee that the condition is true the first time around (so no need to check it)

Maybe I am still trying to wake up, but can't understand a thing. Do not rely on looping on? Loops are not pre-initialized? :~

How 'bout almighty goto?

Note sure if this is counts because it relies on values not being initialized when entering the loop...

//calculates 5*5
int? product;
int? counter;
do
{
int a = 5;
int b = 5;
if (product.HasValue)
Product.Value+=a;
else Product.Value = a;

if (counter.HasValue)
counter.Value+=1;
else counter.Value = 1;
}
while (counter < b)

3x12=36 2x12=24 1x12=12 0x12=18

Even after many cups of coffee, I've very slow morning. My head is very stiff, anyways let us see.

That is not hard, it can be initialized inside the loop?

and do not rely on looping on

I have no idea what you meant? loops that don't need loop? huh?

Ennis Ray Lynch, Jr. wrote:

huh? then you need the mighty for(;;)

Yusuf May I help you?

Yes, yes of course. (Unless I misunderstand the question.) Although I rarely use do loops at all. Here's one I wrote long ago (2003), it could use some work:

private static int
exec_many
(
PIEBALD.Data.IDatabaseConnector dbc
)
{
int result = 0 ;

string intext  = ""        ;
string prompt  = "\\nDBT> " ;
string command = ""        ;

System.Console.WriteLine ( "Enter SQL commands here\\nEnd each command with a semi-colon (;)\\nType \\"exit\\" to stop\\n" ) ;

do
{
    System.Console.Write ( prompt ) ;
    intext = System.Console.ReadLine() ;

    if ( intext == null )
    {
        if ( command == "" )
        {
            intext = "exit" ;
        }
        else
        {
            intext = ";" ;
        }
    }

    if ( intext.StartsWith ( "--" ) )
    {
        continue ;
    }

    prompt = "...> " ;

    command += " " + intext ;

    if ( (intext.Trim()).EndsWith ( ";" ) )
    {
        result += exec\_one ( dbc , command ) ;

        command = "" ;
        prompt = "\\nDBT> " ;
    }
}
while ( intext.ToUpper() != "EXIT" ) ;

System.Console.WriteLine ( "Thank you" ) ;

return ( result ) ;

}
