How Do I Create Multiple Objects Without Declaring Them, With A Loop?

Klear · 2004-03-25T03:22:59

Hello All!, I am creating a loop that creates 6 clocks with random time zones. What I am unclear on is this: How do I create multiple objects without actually declaring them? I am trying to have a loop do it all for me. Do I do it by this?: Clock clock[y] ???? How do I add a letter or number to the end of the name of the object so it differs from the other? Thanks! for ( int y = 0; y < 7; y++){ Clock clock[y] = new Clock(timeZoneIds[random], xplace, yplace); xplace += 100; yplace += 100; clock.draw(page); } [edited by - Klear on March 24, 2004 5:02:34 PM]

you didn''t copy his code right:

Clock clock[] = new Clock[7];

NOT

Clock clock = new Clock[7];

Clock ** clocks

clocks = new (Clock *)[7];

for(i=0;i<7;++i)
clocks = new Clock();

This is so ugly, why a double pointer, newing an array with a cast etc ?
A class is stored as a pointer anyway, so why this indirection ? Why not just

Clock clocks[7];
for(i=0;i<7;i++) {
clocks = new Clock();<br>} </i>

Ugly? UGLY?! Well, how about THIS!

void DoStuffL(){  RPointerArray< Clock > iClocks;  for ( TInt i = 0; i < 7; ++i )  {    Clock *iClock = Clock::NewL();    CleanupStack:: Push( iClock );    iClocks.Append( iClock );  }  for ( TInt i = 0; i < 7; ++i ) CleanupStack:: Pop();}

(I'm sure someone who actually knows symbian can point out quite a few mistakes with that code. And I thought microsoft's code looked bad..)

Why can't you just do
Clock clocks[7]?

Oh, you have a non-trivial ctor, that's why. Evil, pure evil.
