You can often tell how good a developer is by seeing how they construct multiple classes and make them work together.
For this challenge, your tasks are to finish designing three classes: World, City, and Citizen.
For this task, finish the code below so that:
- the program successfully creates a 'world' object
- the program successfully adds 100 cities into the world object using add_city method.
- your program should create these cities with random city name that's 5 characters long and composed of alphabets (use lowercase).
- when a new city is created, it automatically adds 50 citizens to the city, with each citizen having a random age between 0 to 100.
World class needs to have
- a method called add_city - where you can pass the city name and it adds to its list
- an attribute called cities - where this would be an array containing all the city object
- constructor(num) - that creates num number of cities. for example new World(50) should create 50 new cities and store this.
- a method called random_city - where it pulls out a random city object
- a method called total_cities() - that returns the total number of cities in this world
City needs to have
- constructor(name) - that creates a new city with the given 'name' or if 'name' is blank, it can automatically create a random city name that's 5 characters long and composed of lowercase alphabets.
- a method called add_citizen - where you can create a new citizen
- an attribute called citizens - where this would be an array containing all the citizen objects
Citizen needs to have
- a constructor
- when a new citizen is created, it needs to automatically assign a random age (between 0 to 100)
Make sure your code meet all the requirements above and not only rely on the test case to make sure your code is complete. As in real life, test cases do not capture all cases and on this particular challenge, we'll intentionally not add all test cases, so that you're still reviewing your code and checking all scenarios.
Enjoy! Please note that this is not an easy challenge and may take you some time but it is a good practice to get really familiar with OOP and prep for technical interviews.
