Need Help??

ok.. the code is bad. That situations cause problems to novices

$value=5 <------ ok that is the problem it does not have ;
do{
  print "$value\n";
  $value=$value-1;
} while($value>10);
[download]

ok the correct code is

$value=5; # now have ;
do{
  print "$value\n";
  $value=$value-1;
} while($value>10);
[download]

have a fun

Actually, I think the problem is larger than that. shouldn't it be: `$value = 15; # 15, not 5. 5 doesn't make sense if we're not increment +ing. do { print "$value\n"; $value = $value - 1; } while($value > 10);` [download] jdporter fixed formatting	[reply] [d/l]
Re^3: do while loops by Roy Johnson (Monsignor) on Jan 20, 2006 at 22:25 UTC
The point was that the test happens at the end, so the loop executes once even if the value starts out < 10. Caution: Contents may have been coded under pressure.	[reply]
