Show transcribed image textWrite 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.
