Developer Programming Test

Instructions:

Do each of these tasks below in order.  We are looking to see 

1) How many you can get get done in the time alloted

2) How you solved each problem

If you feel the need to explain your thinking for any change, then comment that line with your explanation 

If you cannot complete a task, then move onto the next task.

Task:

1. Run the current program and find and any bugs based on the output.  The expected output should be "NAME is AGE years old" for each object printed in Program.Main.

2. Add an entity class and move the Person.Name property to this new class

3. Have the Person class inherit from this new Entity class

4. Create a new "Address" class and add 4 string properties {Street, City, State, PostalCode} and have the Entity class reference this property

5. Have the "doc" object in Program.Main set the city to "Atlanta"

6. Enhance the print method to display the city by appending either " and they live in CITYNAME" or append " and they are missing the city" depind if the value is filled or not

7. Only doctors can have a HireDate so add a HireDate property to the appropriate class of type DateTime and set this property on the doc object to the current date and time

8. Create a function on the Doctor class to print "They were hired on MM/DD/YY" where MM/DD/YY is the formated string of their hire date.

    The Program.Main will only call doc.Print and it should print the "NAME is AGE years old and they live in CITYNAME" on one line and "This person was hired on MM/DD/YY" on another line.

    I do not want Program.Main to call 2 different print functions for doc.  Only one.

9. Add a property that is a list of the included PhoneNumber class to the class you think it belongs to the best.  Everyone has a phone number.

Using the phone numbers in static function DatabasePhoneNumbers in the class below 

10. In Program.Main ... add the correct phone numbers to the "pat" and "doc" objects using the appropriate key assigned to each person

11. Enhance the print method to only display the phone numbers assigned to the property that have IsSMS set to 1.  Display these phone numbers in sequential order 

    The output would look like "NAME is AGE years old, phone numbers are (XXX) XXX-XXXX,(XXX) XXX-XXXX and they live in CITYNAME "

    There might be 1 or more phone numbers so display all of them comma delimited
