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

Two-Dimensional Arrays
A Two-dimensional array X (7,9) is stored linearly column-wise in a computer's memory. Each element requires 8 bytes for storage of the value. If the first byte address of X (1,1) is 3000, what would be the last byte address of X (2,3)?

use the formulae X(i,j)=Base+w[n(i-1)+(j-1)] where m=7 ,n =9 ,i=2 ,j=3 hence 3000+8*[9(2-1)+(3-1)] =3000+8*(9+2) =3000+8*11=3088

where m=7 ,n =9 ,i=2 ,j=3
hence 3000+8*[9(2-1)+(3-1)]
=3000+8*(9+2)

Why contructors does not supports visual functions?

Editorial / Best Answer
Sandhya.Kishan- Member Since Mar-2012 | Apr 17th, 2012
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.

Thinks of a situation where you need to do some work just once in a function irrespective of how many times that function is invoked then u can have a static variable which will keep a track of it. eg int main () { static int once = 0; if (!once) { once++; /*code need to be executed once*/ } /*reset of the code*/ }
