Definitive answer as to which is faster and why a++, a=a+1,etc.


I know that ++a is faster than a++ because a++ has to first store
the previous value of a at some temporary location and then increment
a and then return the saved value, whereas ++a simply increments a and
returns the pointer to the incremented value.

Since, both a++
and ++a are using a=a+1 as an intermediate step, wouldn't using a=a+1
itself be faster than a++ or ++a ?(since we're not returning an
pointer here)

What about a+=1 ? Is it translated simply to
a=a+1 and does this have a speed penalty.

There is a lot of
confusion as I see it, on the net. Plz help

Okay, I feel that I have to ask this question after looking
through so many threads already attempting to answer this question
giving a whole plethora of answers to probably the most fundamental
request of so many webmasters.
How do I center all webcontent
horizontally and vertically that works with all browsers IE5, IE6,
Safari, Firefox, Mozilla and on both Macs and PCs and is either
transitional HTML 4.01, transitional XHTML 1.0, or strict HTML4.01 or
strict XHTML1.0?
I don't care if it uses CSS or tables or
anything. If this is not possible to do with any of these doctypes,
then I will stick with not using doctypes and nesting a table within a
table and

There seems to be confusion about whether OVI will support wallpapers
and sceensavers.

Flash content (SWF files) that can be used for
screensavers and wallpapers will not be supported in Ovi Store. />So to answer your question, if your Flash content is a SWF file
that's a screensaver or wallpaper then you won't be able to submit it.

C & C++ & C#

I own a HP system, I don't usually buy brand name systems but this
system had all that I required.

It came with a 500gig HD (Sata)
and preinstalled Vista Premium and no backup disks. The harddrive has
a factory recovery partition, unfortunately to recover my system using
this partion also requires re-installing all the trial software the
system came with.

I've downloaded all the chipset drivers
pertaining to my machine and burnt them to a cd.

Among the
chipset drivers is my Serial ATA Controller Driver. I'm purchasing
Vista Ultimate not the upgrade. I want to format and install Ultimate
thus also getting rid of the trial software.

The installation
will be

Alright, a lot of people seem to have problems booting to their hard
drives, but I'm not sure that they have had the same situation as I
have. I've searched the forums, and it seems like the threads who have
a very similar situation are unanswered, so I thought I would try and
ask myself. Here goes:
I'm installing Hardy on my machine. I had
to choose Safe Graphics mode to get it to boot into LiveCD (just FYI,
I dont' think that really has any bearing on the siutation). My
machine is an Asus M2N-E, with 2 SATA drives, and one IDE cdrom. On
the first drive, sda, I have one primary partition, which is ext3,
mounted to /, boot flagged.
The second drive simply has a
