What languages are used in Unicode?
There are very few modern languages that cannot use Unicode. Unicode can also be used from some obsolete languages as well, such as ancient Akkadian, Ugaritic, Old Persian. and so forth. The most basic Egyptian hieroglyphics will be added in the next version, 5.1 along with
The Unicode website at http://www.unicode.org/standard/WhatIsUnicode.html provides the English phrase "What is Unicode" translated into 48 languages and there are far more than that not do not appear here, for example all current American Indian languages that use a version of the Latin script or which use the Unified Canadian Aboriginal Syllables are covered by Unicode.
We are told at http://www.unicode.org/versions/Unicode5.1.0/ that Version 5.1 of Unicode due out next week "extends support for languages in Africa, India, Indonesia, Myanmar, and Vietnam, with the addition of the Cham, Lepcha, Ol Chiki, Rejang, Saurashtra, Sundanese, and Vai scripts."
Accordingly when this question appears in the Unicode FAQ at http://unicode.org/faq/basic_q.html#16 , the consortium's answer is:
"It's hard to say. Many scripts (especially Latin) are used for a very large number of languages. The easiest answer is that Unicode covers all the languages that can be written in the following scripts: Latin, Greek, Cyrillic, Armenian, Hebrew, Arabic, Syriac, Thaana, Devanagari, Bengali, Gurmukhi, Oriya, Tamil, Telugu, Kannada, Malayalam, Sinhala, Thai, Lao, Tibetan, Myanmar, Georgian, Hangul, Ethiopic, Cherokee, Canadian-Aboriginal Syllabics, Ogham, Runic, Tagalog, Hanunóo, Buhid, Tagbanwa, Khmer, Mongolian, Limbu, Tai Le, Han (Japanese, Chinese, Korean ideographs), Hiragana, Katakana, Bopomofo, Yi, Linear B, Old Italic, Gothic, Ugaritic, Deseret, Shavian, Osmanya, and Cypriot.. See also the list of Languages and Scripts. [MD]"
Note that this leaves out some of the scripts in Unicode 5.0 (such as some Philippino scripts) as well as some of the scripts to come in version 5.1. Modern languages still missing would those of small minority communities with unique scripts where no-one has come forth the present the encoding and the Unicode consortium has not got around to doing so themselves as yet. I some cases there is dispute about how a script should be encoded.
The intention is that almost very language known should be encoded in Unicode, with the exception of some modern invented languages of dubious importance. Essentially, if those using such languages don't themselves use a script different from Latin or Arabic or such, even though one may have been invented, then it is not going to be encoded. The only such script which has been rejected (for the moment) from Unicode is Klingon, because the supposed alphabet is rarely used even by those who known Klingon and was not used with the supposed proper values in the flms themsleves. This is the only that I know about where a script was rejected.

Write algorithm of a largest number in three numbers?
1. Read the 3 nos a,b,c
2. Let larget = a
3. if b > largest then largest = b
4. if c > largest then largest = c.....
If you have to process more nos, read all of them in an array. Assume the first element be largest, do comparison through all elements of the array....
Similar algorithm can be developed for finding the lowest also.

How do you uninstall silverlight?
If you want to uninstall Silverlight from your system, you can try Perfect Uninstaller which is the best application removal software to help you uninstall/remove/delete any unwanted programs including Silverlight in order to release more hard drive space for your system.
You have to correctly identify the type of data, for storage efficiency, but even more important, to have the required flexibility. For example, you may decide to store a telephone number as a number. Later you find out that this is an invitation to trouble: if you define it as a number, you can only store digits, but no hyphens, spaces, or parentheses. So, in this case, some kind of alphanumeric data type (text, string; names vary in different programming languages) is more appropriate.
You should give your variable names so that they can be recognized. In a quick exercise, you may work with 3 or 4 variables, so you won't notice the difference. But in a real-world program, you may have scores, or hundreds, of variables; program maintenance would be a nightmare if you can't figure out what several of the variables are used for.

What does eraser have to do with you?
a laundress, newly moved to Charleston following the Civil War, found herself awakened at the stroke of twelve each night by the rumble of heavy wheels passing in the street. But she lived on a dead end street, and had no explanation for the noise. Her husband would not allow her to look out the window when she heard the sounds, telling her to leave well enough alone. Finally, she asked the woman who washed at the tub next to hers. The woman said: "What you are hearing is the Army of the Dead. They are Confederate soldiers who died in hospital without knowing that the war was over. Each night, they rise from their graves and go to reinforce Lee in Virginia to strengthen the weakened Southern forces."
The next night, the laundress slipped out of bed to watch the Army of the Dead pass. She stood spell-bound by the window as a gray fog rolled passed. Within the fog, she could see the shapes of horses, and could hear gruff human voices and the rumble of canons being dragged through the street, followed by the sound of marching feet. Foot soldiers, horsemen, ambulances, wagons and canons passed before her eyes, all shrouded in gray. After what seemed like hours, she heard a far off bugle blast, and then silence.
When the laundress came out of her daze, she found one of her arms was paralyzed. She has never done a full days washing since.
She lived deep in the forest in a tiny cottage and sold herbal remedies for a living. Folks living in the town nearby called her Bloody Mary, and said she was a witch. None dared cross the old crone for fear that their cows would go dry, their food-stores rot away before winter, their children take sick of fever, or any number of terrible things that an angry witch could do to her neighbors.
Then the little girls in the village began to disappear, one by one. No one could find out where they had gone. Grief-stricken families searched the woods, the local buildings, and all the houses and barns, but there was no sign of the missing girls. A few brave souls even went to Bloody Mary's home in the woods to see if the witch had taken the girls, but she denied any knowledge of the disappearances. Still, it was noted that her haggard appearance had changed. She looked younger, more attractive. The neighbors were suspicious, but they could find no proof that the witch had taken their young ones.
Then came the night when the daughter of the miller rose from her bed and walked outside, following an enchanted sound no one else could hear. The miller's wife had a toothache and was sitting up in the kitchen treating the tooth with an herbal remedy when her daughter left the house. She screamed for her husband and followed the girl out of the door. The miller came running in his nightshirt. Together, they tried to restrain the girl, but she kept breaking away from them and heading out of town.
The desperate cries of the miller and his wife woke the neighbors. They came to assist the frantic couple. Suddenly, a sharp-eyed farmer gave a shout and pointed towards a strange light at the edge of the woods. A few townsmen followed him out into the field and saw Bloody Mary standing beside a large oak tree, holding a magic wand that was pointed towards the miller's house. She was glowing with an unearthly light as she set her evil spell upon the miller's daughter.
The townsmen grabbed their guns and their pitchforks and ran toward the witch. When she heard the commotion, Bloody Mary broke off her spell and fled back into the woods. The far-sighted farmer had loaded his gun with silver bullets in case the witch ever came after his daughter. Now he took aim and shot at her. The bullet hit Bloody Mary in the hip and she fell to the ground. The angry townsmen leapt upon her and carried her back into the field, where they built a huge bonfire and burned her at the stake.
As she burned, Bloody Mary screamed a curse at the villagers. If anyone mentioned her name aloud before a mirror, she would send her spirit to revenge herself upon them for her terrible death. When she was dead, the villagers went to the house in the wood and found the unmarked graves of the little girls the evil witch had murdered. She had used their blood to make her young again.
From that day to this, anyone foolish enough to chant Bloody Mary's name three times before a darkened mirror will summon the vengeful spirit of the witch. It is said that she will tear their bodies to pieces and rip their souls from their mutilated bodies. The souls of these unfortunate ones will burn in torment as Bloody Mary once was burned, and they will be trapped forever in the mirror.
A segment address is the contents of a segment register, CS, DS, ES, or SS. It is used after effective address generation to provide an offset in physical memory, by multiplying the segment register by 16 and then adding it to the effective address, giving a 20 bit address.
This gives you addressability to 65536 segments of 65536 bytes, each separated by 16 bytes.
The register used is usually implicit based on use; CS for code, DS for data, ES for certain string operations, and SS for stack. A segment override prefix can be used to select a different segment register.
Press the Print Screen button which is on your keyboard. Go to the application you want to put it in and then go to the Edit Menu and choose Paste. A full screen shot will appear. Using Alt and the Print Screen button will allow you to take a copy of just the open window or dialog box, instead of the entire screen.
Sixteen would be coded 10, similar to ten being coded 10 in decimal: One in the 'sixteens' column, and zero in the units column. It's a wonderful question, though. The mystery evaporates when you realize that we commonly use a 'decimal' system, but the value of the highest single-digit number is 9.
It seems odd, but think of the number line as a representation of continuous values. There are 10 ranges of value BETWEEN 0 and 10. These ranges can be coded with numbers between 0.000... and 9.999... The same idea applies to the hexadecimal system. F has the value of decimal 15.
What is the keyboard shortcut to open the 'Save As' dialog box?
It depends on the application. Not all applications provide shortcuts for each and every command, although most will provide the conventional ones (CTRL-S for File>Save, CTRL-N for File>New, CTRL-C for Edit>Cut, and so on). SHIFT-CTRL-S is a reasonably common user-defined shortcut for the File>Save As... dialogue, however for application-specific help you'll have to consult the application's documentation.
What is bigger than a einsteinbyte?
Whomever gave this name to you was probably being sarcastic (as in, "You're no Einstein."). The other apparently related question "What is a coperbyte?" is also apparently bogus in nature.
The largest value identified by the International System of Units (SI) is a "yottabyte", which is approximately the size of all the known Internet in bytes, and exceeds the far exceeds the number of bytes it would take to transcribe every word ever spoken in human history.
There is no larger "official" size than that. As a matter of course, it is unlikely that an "Einsteinbyte" would ever be termed, because each magnitude of bytes beyond the first are all named with Greek prefixes; Einstein is a complete word by itself, not a word part defined as a prefix. It would have been more believable had they called it an "einbyte" or some such.
There is a Wikipedia entry in regards to "Non-SI unit prefixes" that includes brontobyte, supposedly the size after yottabyte and before Geopbyte (the latter named at whatsabyte.com). It notes that those values are non-standardized in terms of magnitude, and are not recognized by any real community.
For now, you should accept that 999, 999, 999, 999, 999, 999, 999, 999, 999 (or 1, 237, 940, 039, 285, 380, 274, 899, 124, 223 using binary notation's "yobibyte") is the largest value that has a name using today's standards. Adding 1 to the values above to advance to the next magnitude would result in an value that has no standard name.

Write a function to delete a specified node from linked list?
Presumably you have a situation like this:
Each node is an area in memory with (1) the address of the following node, (2) the address of the previous node, and (3) some more data.
Say the nodes are linked in alphabetical order and part of the list goes like this:
PrevNode
-> Data = "Cincinnati"
-> FrontPtr = address of "Cleveland"
-> BackPtr = address of "Amelia"
CurrNode
-> Data = "Cleveland"
-> FrontPtr = address of "Columbus"
-> BackPtr = address of "Cincinnati"
NextNode
-> Data = "Columbus"
-> FrontPtr = address of "Dayton"
-> BackPtr = address of "Cleveland"
...and you want to delete the middle one. Steps could be:
1. save the address of CurrNode as KillNode
2. copy CurrNode->FrontPtr (address of "Columbus") into
PrevNode->FrontPtr
3. copy CurrNode->BackPtr (address of "Cincinanti") into
NextNode->BackPtr
4. free up the space at the location named in KillNode
Can a magnet delete everything on a computer by just putting it on the outside?
No. A magnet only interfers with magnetic fields ... lots of old IBMs used magnetic memory cards and that's where the stories started.
It might erase a floppy disk, but an electro-magnet does the job much better than a perminant magnet.
What is a Pure Virtual Function Write a C plus plus program using Pure Virtual Function?
A pure-virtual method is similar to a virtual method. A virtual method is a method that is expected to be overridden in a derived class while a pure-virtual method must be overridden in a derived class. The base class may provide a default implementation for a pure-virtual method, but it is not a requirement, whereas it must provide an implementation for a virtual method. In addition,
any base class that has a pure-virtual method becomes abstract; you cannot instantiate abstract classes -- you are expectedto derive from them.
#include
class Abstract
{
public:
// Pure-virtual method; note the '=0' to denote pure-virtual.
virtual void Show()=0;
};
class Derived : public Abstract
{
public:
virtual void Show()
{
// Implementation is required here!
std:: cout << "Derived" << std::end;
}
};
void main()
{
// Abstract a; // Compiler error!
Derived d;
d.Show(); // Call pure-virtual method.
return( 0 );
}
Can arithmetic be performed in the A register?
On platforms with specialized registers, the A register is usually an accumulator, whose primary function is to store the results (and possibly provide a parameter of) an arithmetic function. In Intel code, for example, add ax,bx adds the contents of ax and bx together, and stores the sum in ax. RISC processors generally do not have specialized registers in this sense, and instead name most their registers generically (e.g. r0, r1, r2...). This allows any general register to perform any general function, including arithmetic. For specific chip dialects, please refer to that chipset's programming manual.
