Write a C++ program that does the following:

Create a class called Automobile
This class has the following private attributes:
- model
- year
- mileage
This class has the following methods:
- Default constructor
- Non-default constructor that will initialize all the above attributes
- Set/Get method for each of the above attributes
- displayAuto that will print the information for the Automobile all three attributes on the same line with proper spacing
- Destructor method that will print a message that the object has been deleted
Create a class called Inventory
This class has the following private attributes:
- count: This represents how many current automobiles in the inventory
- maxCount: This represents the maximum number of automobiles that can be stored
- autoPtr: A pointer to Automobile objects.
This class has the following methods:
- Default constructor (count is 0, maxCount will be 10, autoPtr is NULL)
- Non-default constructor that will have one integer parameter
  - count will be initialized to 0
  - maxCount will be set to that one parameter passed
  - autoPtr will be allocated enough space to accommodate enough objects equals to the maxCount. Basically, you will use the new operator to allocate space for an array of Automobile objects.
- addAutombile to append a new automobile to the inventory and update all the needed attributes. This method needs to check to see that you have not exceeded the capacity of the inventory
- displayInventory method that will call displayAuto method to display the content of the inventory
- Destructor method to make sure everything is cleaned up especially the memory allocated for the pointer. Also display a message that you called the destructor of the Inventory class.

Your main function should do the following
- Ask the user how many automobiles to create
- Define the appropriate variables as needed
- Create an Inventory object and call the non-default constructor for that object with the number of automobiles given by the user
- Use a do..while loop to display the menu with the following options:
  - 1: Add an automobile to the inventory
  - 2: Display the content of the inventory
  - 3: Display the automobiles below certain mileage
  - 4: exit
- Your code should ensure that user inputs a valid choice (1..4) only
- If the user choses “1”, this should call a function called addNewAuto. This function will take the Inventory object as a parameter and then call the addAutomobile method to add the new car
- If the user choses “2”, this should call the displayInventory method of the Inventory object
- If the user choses “3”, this should call a function called searchAuto. This function will take the Inventory object as a parameter and then ask the user for the mileage. Then it will display all automobiles in the inventory below that mileage.
- If the user choses “4”, the system will exit.
