How do you pass a class in programming cplusplus?
A class is a type. You cannot pass a type in C++, you can only pass an object of the type, either by value or by reference.
The only way to physically pass a type is to pass a void pointer (void*), then use expensive runtime type information to determine the runtime type of the object being referred to. However, it's much more efficient (and easier) to simply pass a base class that provides the generic (virtual) interface required by your function.
What is the shell script program for adding five digit numbers?
It depends upon which language you intend to write your script, however 5 digit numbers are simply numeric value and any scripting language that supports basic arithmetic operators will be able to achieve this easily. The hardest part is converting the user input (which is typically a character sequence) into an actual number, however most scripting languages will provide some means of converting strings to numeric values.
Multi-tasking.
If you declare an integer array as int num 20 45 56 12 19 34 what is the value of num3?
The element at offset index 3 is 12.
int num[6] {20, 45, 56,12, 19, 34};
assert (num[3]==12);
A compiler.
I just searched for the game on Wikipedia - it listed the following system requirements...
2.4 Ghz processor
256MB video card
1GB RAM on XP \ 2GB on Vista
DirectX version 9.0c or better
15GB hard disk space
Comparing those specifications with the ones you listed - you should be able to play it without any problems, although your slower processor speed might cause the game to lag.
What is the meaning of FAT in computer science?
File Allocation Table
Also rarely used anymore. Most systems use NTFS (New Technology File System) which tends to be more user friendly. It was released with the Windows NT (New Technology) OS and has been the preferred file system ever since though the OS itself was not so good.
What is an An address embedded in a file that links the file with an object?
It is poor programming practice resulting in undefined behaviour. Files should never store memory addresses (real or virtual), since there's no guarantee a valid object will always reside at the same location in memory, unless the programmer can be absolutely certain the object will outlive the file (such as when referring to active objects in memory via a temporary file).
To embed an object in a file, the object must be stored in an independent file. The file in which the object is embedded simply links to the object's file. In this way, whenever the object is updated (and saved), all files in which it is embedded will also be updated.
There is no scanf in Java. It is one of the keywords used in C Programming language
What company has Mercury as a logo?
Mercury Logo FTD otherwise known as Ford Motors the FTD logo is used by flowershops that deliver flowers across the nation.
How to Differentiate Thesaurus from Checking the spelling and grammar?
I'm not sure I understand what you mean by differentiate, but if you are using the grammar and spelling checker in Word, you have options. For instance, when the checker stops on questionable spelling and/or grammar, you can click to check grammar (uncheck if already checked). If you click on options on that page, you can choose your own rules by checking/unchecking the boxes. Hope this helps!
Which encryption algorithm is better and why?
If you're talking about symmetric key encryption (the kind where you just use one key for encryption and decryption), then arguably, the best encryption algorithm you can use is the Rijndael algorithm, better known now as AES (advanced encryption standard). It is the encryption standard used by the U.S. government for classified information. It is fast, requires little memory, and the only potential attacks against it are highly theoretical.
Rijndael beat out Twofish and Serpent in the AES standard contest, but those other two algorithms will provide more than enough security as well. In the end, it doesn't really matter, since most successful attacks are made simply by finding out your key through brute force, espionage or extortion, rather than pure data analysis.
Humans are almost always the weakest point when it comes to security, and it doesn't matter what algorithm you use if someone can guess your password.
Is C programming works without assembler compiler interpreter?
No, a C program cant work without an interpreter or compiler or assembler as the code written in the program is not understood directly by the computer so it needs any of the above translator program to make the program understandable to the computer.
-Shruti JainMy windows 7 is activated but my product key doesn't work why?
If the key doesn't work then it can't be activated. If it's activated you don't need a key. If it's not activated and the key doesn't work, contact Microsoft support.
When can computer retrieve data?
yes. It does so every time you open a new brower, website or anything online. Once you type in the adress of the site, the computer goes to the IP adress and retrieves the data that the computer on the other end provides. This way, hackers provide a virus through; so you need to be careful on what site you go to.
Lexical analyzer generators translate regular expressions (the lexical analyzer definition) into finite automata (the lexical analyzer).
For example, a lexical analyzer definition may specify a number of regular expressions describing different lexical forms (integer, string, identifier, comment, etc.). The lexical analyzer generator would then translate that definition into a program module that can use the deterministic finite automata to analyze text and split it into lexemes (tokens).
A motherboard is the main printed circuit board found in computers. It holds many of the electronic components of the system such as the central processing unit, memory, and provides connectors for other devices.
How Rapid Application Development RAD supports event driven programming?
First of all this sounds like an exam/assignment question you have to do. Therefore I'm not going to do it for you, some food for thought though - Event Driven Programming is generally very quick and straightforward to produce working copies of application. As I'm sure you know RAD works by creating prototypes quickly and testing these. Therefore I'm sure you can work out the link.
Enjoy your homework sire ;)
Yes. Some software vendors can do this for their own programs. There's one that will repair XP over the internet.
