Create a class named 'Rectangle' with two data members- length and

breadth and a function to calculate the area which is 'length*breadth'. The

class has three constructors which are :

1 - having no parameter - values of both length and breadth are assigned

zero.

2 - having two numbers as parameters - the two numbers are assigned as

length and breadth respectively.

3 - having one number as parameter - both length and breadth are

assigned that number.

Now, create objects of the 'Rectangle' class having none, one and two

parameters and print their areas.
