What's wrong with this code ?

[devilinthebox]

It has to do this

"10...9...8...7 ...6...5...4... 3...2...1...0 BLAST OFF!"

c.println ("Count Down");
int num = 10;
while (num<10)
{
c.print (num + " . . .");
num = num - 1;
}
c.println ("BLAST OFF!");

It just says
" Count Down
BLAST OFF!"

Here's a small question to you: if 'num' equals 10 is it smaller than 10?

kind regards,

No it's not.... I still don't understand what's wrong with the code though.

Because 10 is not less than 10, you never enter the loop. Also, note that if you change it to <=10, you're going to get an infinite loop.

Just in case:
What is being said is change your statment to

while (num >= 0)

That way it will Count down to 0

The way you have it now basically your statement says;

While (10 < 10)
{
do the stuff in here.
}

Trust me I've done this once or twice myself.... but never a third time tankfully.

By the way, there's not only one kind of loop - try something similar to this in future:
[CODE=java]
for(int i=3; i>=0; i--)
{
// do something
}
[/CODE](Yes, for-loops can go BOTH ways... ^^)
