Write the class specification of a class Phone containing: 1. A data member named model of type string (private). 2. A data member named partNumber of type string (private). 3. A data member named retailPrice of type double (private). 4. A default constructor that intializes model and partNumber to empty strings and retailPrice to O 5. getter (accessor) functions that return the value of each of the data members 6. setter (mutator) functions to set each of the data members 7. Overloaded stream insertion operator () that reads the data members from an input stream (format: model, part number, retail price) Note that you’re NOT asked to implement any member functions of the class. Write only the class specification.
