Answer / madhu

In C++ when you declare and define a static variable, it
tells the compiler that only one copy of memory will be
allocated and all the objects of that class will share that
copy.
As we know for class data variables memory will be created
independently for every object of that class. and we can
access the data using object. But, for static variables
memory is created only once for all objects and is no object
is owned the static variable. we can access the static
variable using class name.

Mainly static variables are used when want to count the
objects created and destroyed and when we are dealing with
singleton design pattern.
