Answer Posted / shabeer v c

A good example to illustrate this Question ges like this:

Whenever we apply for a job the company declares that we
have been selected. Similarly we declare a variable like

int emp;
(here emp behaves as an employee).

Then he will be assigned with a initial salary which
will be incremented in course of time period or on
experience basis.
Similarly the variable int is assigned a initial
value.
i.e int emp=20;
(value can be changed in between program)

The employee is now identified by his post, which can
define his status in the company.
Same way the variable is also defined in the
program.
ie. int emp;
