A Car Showroom is composed of halls. Each hall has a name, length, width and a number of cars on display. Each car has model, color, company name. The Showroom will have a name and location. Showroom name cannot be modified. All other attributes can be modfied. (If you have made any attibutes constant and you are not getting any problems, then continue working like this). You should count how many cars are present in the Showroom.

Make object model for the above scenario and implement it. User can make objects of Showroom class in main. User should be able to:

• print info of all the halls
• print all cars of a specific hall
• print all cars of the Showroom categorized by halls
• display number of cars in a specific hall
• increase/decrease number of cars in a specific hall
• increase/decrease halls in the showroom
• view any attribute of any hall
• view any attribute of any car (in any hall)
• change any attribute of any hall
• change any attribute of any car (in any hall)
• display all cars of a specific color in all the halls (categorized by halls)

Follow the normal coding conventions like declaring maximum possible functions as constants, passing maximum possible arguments as constants, declaring all attibutes as private, etc.

HINT: You'll have to make pointers to store dynamically allocated arrays of objects so that the size of these arrays can be increased/decreased. Remember which two functions should be written in a class when you have a pointer in the class?
