By using #pragma pack(1) we can reduce the size of structure.
Code- #pragma pack(1)

What is virtual Memory under Linux?
Read Best Answer
Editorial / Best Answer
Answered by: Hitesh
- Jan 3rd, 2007
Linux supports virtual memory, that is, using a disk as an extension of RAM so that the effective size of usable memory grows correspondingly. The kernel will write the contents of a currently unused block of memory to the hard disk so that the memory can be used for another purpose. When the original contents are needed again, they are read back into memory. This is all made completely transparent to the user; programs running under Linux only see the larger amount of memory available and don't notice that parts of them reside on the disk from time to time. Of course, reading and writing the hard disk is slower (on the order of a thousand times slower) than using real memory, so the programs don't run as fast. The part of the hard disk that is used as virtual memory is called the swap space

Editorial / Best Answer
Sandhya.Kishan- Member Since Mar-2012 | Jul 4th, 2012
Raster data is a set of horizontal lines composed of individual pixels, used to form an image on a CRT or other screen.Raster data makes use of matrix of square areas to define where features are located. These squares are typically of uniform size, and their size determines the detail that can be maintained in the dataset.Raster data represent square areas, they describe interiors rather than boundaries. Vector data use X and Y coordinates to define the locations of points, lines, and areas (polygons) that correspond to map features, vector data tend to define centers and edges of features.They are excellent for capturing and storing spatial details

Constructor does not support virtual functions because we need an object to invoke a virtual method in the first place and more over constructors are used to initializing objects,which is a static type.Virtual functions are invoked on the dynamic type of the object,hence the object may not be properly initialized when a constructor call is made.Since the derived part of the object would not be initialized during the execution of base class constructor,hence calling any virtual method from base class constructor does not work well.

What is the main difference between portability and Platform independent ?
Read Best Answer
Editorial / Best Answer
Lecks- Member Since Feb-2010 | Feb 22nd, 2010
I agree it is correct to say that Java is platform independent, but it is due to the Java Virtual Machine. Java programs are only intermediately compiled, which allows adaptation to the given environment it needs to run in later.
An example of a portability issue is the creation of Unix. The first version was not portable. It was specific only to that computer's architecture. Unix became portable when it was rewritten in C. The new version written in C was portable because C served as a "translator", if you will, between what underlying architecture or devices were physically in the computer and what unix wanted them to do.Lecks

Editorial / Best Answer
saradalincoln- Member Since Jun-2007 | Jul 17th, 2007
hi,
1. Take 2 empty stacks.
2. Fill the 1st stack with some items (eg: input 100, 101, 102, 103)
3. Now read the items from 1st stack in LIFO order and write to 2nd stack.
(By this the 2nd stack will get the items in the order .. 103, 102, 101, 100)
4. Now read the items from 2nd stack in LIFO order i.e. the output will be
100, 101, 102, 103.
(this is the queue order FIFO with respect to the actual items entered in 1st
stack.)

A database is an organized collection of information. It is structured so you can jump to the information by using a key, and find related infromation by navigating a path. A sequential (flat) file is not considered a database.
