Please help with a source code for C++ and also need screenshot of output:

Step 1:

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:

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 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.
