Write C++ program on classes and objects that should demonstrates the followings:

a. Definition of a class (e-g. you can create a \"Rectangle\" class)

b. Class objects (at least three objects)

c. Scope operator

d. Default constructor

e. Copy constructor

f. Constructor with parameters

Your program must include private members of the class \"Width\" and \"Length\", and public members of the class setValues0, getValues, and area0. Also, your program should demonstrate how to set width and length values, how to get width and length values, and how to calculate area of the rectangular objects.
