1. Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities.


2. Create array of countries called Arab of 22 countries. Write a function fill that fills the array Arab


3. Write a method that finds the city that has the max area in a country


4. Write a method that sorts the cities in a country from the largest to the smallest area


5. Write a function that returns array of countries of the same area of Arab


6. Write a function that compares between two countries. It returns true if country1 area greater than country2 area.


7. Write a function to move a city from one country to another.
