* Stack is a kind of data structure where Last In FirstOut
work. Local variables are needed for a short span of time
for immediate processing. So push and pop from stack is
used for them. Now memory is allocated to them in static
time only.
* new() operator allocates memory dynamically. Since
objects are needed for more time, space is taken from heap.
