Of the outer loop or the count of 1, so you need something like:
int stage=0; while(...infinity in another language (Ruby):
4.times {|n| print 10**(n+1)}
System.out.println("1 0 1 0 0 1 0 0 0....

('%03d', $i)
and link to the manual
cheers
printf("%03d", $i);
The idea is you don't count it like", $i); }
str_pad method:
echo str_pad($i, 3, '0', STR_PAD_LEFT);.

Hi folks,
in the System.Linq namespace, we can now extend our IEnumerable 's to have the Any() and Count() extension methods .
I was told recently that if i want to check that a collection contains 1 or more items inside it, I should use the .Any() extension...

If youWell, the .Count() extension method won't use the .Count property, but I would assume you wouldn't use the .Count() method....
In that context, .Any() will be faster than .Count() > 0.
With filtering criteria, etc.

I am trying to find the number of different things in my database, using SELECT COUNT(*). The problem is when there are zero --
For example,
SELECT COUNT(*) FROM `images` WHERE `approved` = '1'
If there are no results, I will still get a 0 back and can...

You can't COUNT(CASE WHEN approved = '0' THEN 1 END) AS Cnt, first_name , last_name , email FROM images GROUP query WITHOUT the....
And that would be acceptable, and THAT count would be equal to 0 where no rows are returned.

I have a report that tracks how long certain items have been in the database, and does so by tracking it over a series of age ranges (20-44, 45-60, 61-90, 91-180, 180+). I have the following query as the data source of the report:
SELECT DISTINCT Source...

You can return
ISNULL(Count( ), 0)
and all should be fine - would be in MS SQL Server - but I just
Nz(Count(SELECT Source.DateAdded FROM Source WHERE Int(Date()-Source.DateAdded), 0)
This will return 0 when the result....

Can't you use.
The number function?
<xsl:variable name="x5" select="number(count($mynodeset) != 0)"/>
I don't reallyJust use the function number() , which converts a boolean value to 1 or 0.

I was wondering if there is a clean way of counting from 0 to 255 using an 8 bit datatype, something like:
for(uint8_t i(0);i<=255;++i) { .... }
This obviously will not work but it makes it clear you want to count from 0 to 255.
A working solution ...
