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*/ }

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

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.
A relational database contains one-to-many relationships.
A networked database contains one-to-many and many-to-many relationships.

Collection of inter-related data is called as database.
A DATABASE WHICH SUPPORTS ALL TYPES OF RELATIONS(one-one,one-many,many-one,many-many)IS CALLED AS RELATIONAL DATABASE.
object database or object oriented database both r same.

Go to the file which you have to check out.Right click and goto "Update" and update the file.Right click on the same file and goto explore.You will find all the files in that particular folder.Now you can copy/paste the required files anywhere in your machine.

There will be a lot of changes in fact. First of all, all the variables the function was suing needs to be pushed into the stack. (we need all these variables when we return from the other function). The Program counter will be pushed to stack too... (When the "return" of second function occurs we should know where to 'return' to)These are the basics which are bound to happen when a function calls another.
