1. Design and implement a class "Window" using The class should have Window ID, size, background colour, topmost location as data members. You may add more data members. The class should have three member functions:

• First member function to input information into data members of an object.

• Second member function to display information stored in an object.

• Third member function accepts a parameter value colour and changes the data member background colour for that object.

Write appropriate main( function which creates five "Window" objects in an array. Your main( function must demonstrate all the member functions.

2. Consider the following class hierarchy with the suggested data members:

Design and implement the classes in the hierarchy using You may add more data members in the classes, if needed. You should include at least one constructor in each class. All the classes should have a member function print_phone_info() which displays all the information of the object of that class. You should demonstrate polymorphism using functions main() and print_phone_info(
