Create a Person class and a Glasses class.

Step One Create a C++ project

• Create a Glasses class using a separate header file and implementation file.
• Add the following attributes.
  • Color (string data type)
  • Prescription (float data type)
• Create a default constructor that sets default attributes.
  • Color should be set to unknown because it is not given.
  • Prescription should be set to 0.0 because it is not given.
• Create a parameterized constructor that sets the attributes to the given values.
• Create a destructor for the class.
• Create a toString( ) method.
  • The toString( ) method should return a description of the object's state (e.g., Color: Black, Prescription: 1.75).
    • You can use the to_string( ) method to convert prescription to a string, or you can create a stringstream object. (Google for more info.)
• Create accessors and mutators for the attributes.

Step 2, you will create a Person class with a Glasses composite attribute. The Person has a Glasses object.

• Create a Person class using a separate header file and implementation file.
• Add the following attributes.
  • Name (string data type)
  • SSN (string data type)
  • myGlasses (Glasses data type)
• Create a default constructor that sets default attributes.
  • Name should be set to unknown because it is not given.
  • SSN should be set to unknown because it is not given.
  • myGlasses should not be created because the attribute line creates a default Glasses object.
• Create a parameterized constructor that sets the attributes to the given values.
• Create a destructor for the class.
• Create a toString( ) method.
  • The toString( ) method should return a description of the object's state (e.g., Name: Bob, SSN: 555-55-5555, Glasses: [Color: Black, Prescription: 1.75]).
• Create a writeToFile( ) method with a string return message that saves the object's state (current attribute values) to a file using the person's name (e.g., Bob.txt).
• Create a readFromFile( ) method with a string return message that reads the object's state from a file using the person's name (e.g., Bob.txt).
• Create accessors and mutators for the attributes.

Step 3 Create a main method for your application to test the functionality of your Composition classes.

• Create a default Person object.
• Create a Glasses object using the parameterized constructor.
• Change the name and SSN of the default Person object.
• Change the myGlasses of the default Person object using the Glasses that you created.
• Display the changed Person object state using its toString( ) method.
• Change the myGlasses of the Person object using an anonymous Glasses object (on the fly).
• Display the changed Person object state using its toString( ) method.
• Show the prescription only for the Person object.
• Show the color of the glasses only for the Person object.
• Write the Person object's state to the file using the writeToFile( ) behavior.
• Create a new default Person object.
• Set the name of the new Person to match the first Person object.
• Read the Person object's state from the file using the readFromFile( ) behavior.
• Display the new Person object's state using its toString( ) method
