Create a class named ’Rectangle’ with two data members- length and breadth and a method 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.
