Computer Viruses

Header linked list are frequently used for maintaining polynomials in memory. The header node plays an important part in this representation, since it is needed to represent the zero polynomial. This representation of polynomial will be presented in the context of a specific

Most programs you can download in source form can be compiled using the following simple steps:

1. Extract the source package (ex. 'tar xzvf programname-version.tar.gz'), this will create directory programname-version. Chdir into it.

2. Run './configure'. This checks the build environment to make sure your compiler works and has the proper libraries installed.

3. Run 'make'. This compiles the program.

4. Run 'make install'. This places the binaries in the appropriate location(s).

5. Depends on GCC version also

Animals can get viruses from humans, but it's not as common due to evolutionary differences between species. Some viruses may not be able to cross the species barrier easily, while others may not cause severe illness in animals. However, viruses like flu can sometimes transmit between humans and animals.

Far Pointer is a pointer that is stored using four bytes (32 bits). The bytes are stored little endian or low to high order. A far pointer can access objects up to 16K in size in any memory area. Objects larger than 16K must be accessed using huge pointers

This book is basic for c , download and Read this... must required !

It is a matter of the memory model you are using. On old or embedded systems, some memory was outside of the range of a normal pointer. If you have 4 megs of ram you need at least a 22bit pointer to see all of it. But let's say you only have a 16 bit pointer. This means you can only access the first 65K of ram. Odd as it may sound, this was a problem on old computers, and is sometimes an issue on embedded devices with limited processing power. The near and far classifications were a solution. Pointers are near by default. In my example above, the 65K of ram would be accessed with a near pointer. To get past that 16 bit limit, you need a far pointer. Thus: memory within the pointer's range is near. Memory outside of the range is far. Near pointer: char near * ptr; Far pointer: char far * ptr;
A far pointer uses both the segment and the offset address to point to a location in memory. A near pointer in contrast uses only the offset address and the default segment. The far pointer can point to any location in memory, whereas the near pointer can only point to a nearby local address.
Something that was important 20 years ago. Now you can forget it.

WHAT IS A CONSTRUCTOR

"It is a special type of method same name as class name that determines how an object is initialized when it's created".

what is constructor in java

Like other methods, we can also define constructor Method in our java program but unlike other methods, we cannot call a constructor directly; Java called constructor automatically when an object has created. When we use new keyword to create an object of a class, java does three thing;

Allocates memory for the object.

Initialize that object instance variable, with their initial value or to a default.

Call the constructor Method of the class.

If a class doesn't have defined any constructor method, we will still create an object of that class but we have to set instance variable or call other methods that object needs to initialize itself to that object afterward.

By defining constructor method in our own classes, we can set initial values of instance variable, call method based on those variable or call methods on other objects, or calculate initial properties of our object. We can also overload constructor, as we would regular methods, to create an object that has specific properties based on the argument we give to new.

BASIC CONSTRUCTOR

by defining a constructor looks like a regular method, with 2 basic difference.

Constructor and class name are always same.

It doesn't have any return type

For example, in the below table a simple class person, with a constructor that initializes it's instance variable based on the argument to new. The class also includes a method for the object to introduce itself, and a main() method to test each of these class.

class Person

{

String name;

int age;

Person (String n, int a)

{

name = n;

age = a;

}

void printPerson ()

{

System.out.print("Hi, I am " +name);

System.out.println(" I am "+ age + " years old.");

}

public static void main(String args[])

{

Person p;

p = new Person ("Ajab", 20);

p.printPerson();

p = new Person ("Rizwan", 30);

p.printPerson();

The output of the program is given below:

Hi, I am Ajab. I am 20 years old.

Hi, I am Rizwan. I am 30 years old

CONSTRUCTOR OVERLOADING

like other methods, constructor can also take different number and types of parameters, enabling us to create our objects with exactly the properties you want it to have, or for it to be able to calculate properties from different kinds of input.

constructor overloading in Java

For example, the MyRectone class in the given table creates a MyRectone Constructor and passing different parameter instead of creating different methods for the given arguments.

class MyRectone

{

int x1 = 0;

int y1 = 0;

int x2 = 0;

int y2 = 0;

MyRectone ( int x1, int x2, int x2, int y2)

{

this.x1 = x1;

this.y1 = y1;

this.x2 = x2;

this.y2 = y2;

}

MyRectone (Point topLeft, Point bottomRight)

{

x1 = topLeft.x;

y1 = topLeft.y;

x2 = bottomRight.x;

y2 = bottomRight.y;

}

MyRectone ( Point topLeft, int w, int h)

{

x1 = topLeft.x;

y1 = top left.y;

x2 = ( x1 + w);

y2 = (y1 + h);

}

void printRect ()

{

System.out.print ("MyRectone: ");

}

public static void main (String args [] )

{

MyRectone rect;

System.out.println ("Calling MyRectone with coordinates 35,35 70,70");

rect = new MyRectone (35,35,70,70);

rect.printRect();

System.out.println ("Calling MyRectone with coordinates (15,15) (30,30)");

rect = new MyRectone (15,15,30,30);

rect.printRect();

System.out.print (" Calling buildRect w/1 point (10,10),");

System.out.println ("width (50) and height (50)");

rect = new MyRectone ( new Point (10,10), 50, 50);

rect.printRect();

Output

Calling MyRectone with coordinates 35,35 70,70:

MyRectone: 

Calling buildRect w/1 points (15,15), (30,30):

MyRectone: 

Calling buildRect w/1 point (10,10), width (50) and height (50):

MyRectone:

CALLING ANOTHER CONSTRUCTOR

Some constructor may be a superset of another constructor defined in your class; that is, they might have the same behavior plus a little bit more. Rather than duplicating identical behavior in multiple constructor Methods in our class, it makes sense to be able to just call that first constructor from inside the body of the second constructor. Java provides a special syntax for doing this. To call a constructor defined on the current class, use this form:

this (arg1, arg2, arg3 …..);

The arguments to this are, of course, the arguments to the constructor.

There are two major categories of programs which utilize event-driven method of their implementation: device drivers and GUI programs. Both spend most of their life cycle in waiting loop and perform any action only upon an incoming event, such as hardware interrupt, or an user's action. Internally, an incoming event may be processed by receiving code or dispatched to further code layers.

a virus

could also be a worm, trojan, etc.

There are viruses in almost every programming language, but most are probably written in C and C++ as these two languages have a lot more control over your application compared to most others, so you can be very specific about what you want them to do. Smaller, less powerful languages such as Visual Basic, .NET, Python or Java will also suffice in creating viruses. Viruses can also be embedded in browser add-ons, and other downloaded things.

It's also possible to embed an HTML virus into a website.

And by the way, I know that "most virus' are written in Asm, and not any high level languages cuz they're too... uh... high, yeah. stupid f*ckin computer geeks, go jump off 21h and land in the stack. anyway, yes, my question (I am Agrybard) is really if there are any virus' written in C++, rather than just C, but either way I would appreciate any help. and yes, I've GOOGLED IT ALREADY! lol AGB

If a hacker has gotten into your computer once, they will get in again. If you are unable to track down any programs that they left behind, you should seek professional help. As a last resort, backing up your important data and reformatting your computer will guarantee removal of these programs.

Remember to always use strong passwords and to be suspicious of any programs you download from the internet.

SOFTWARE is a collection of some programmes which is designed for specific task to be done.while the programme is a set of instruction written in a comp understood language to do a specific work.
