Explanation / Answer

class personType { public: void print() const; //Function to output the first name and last name //in the form of firstName lastName. void setName(string first, string last); //Function to set firstName and lastName according //to the parameters. //Postcondition: firstName = first; lastName = last string getFirstName() const; //Function to return the first name. //Postcondition: The value of the data member firstName // is returned. string getLastName() const; //Function to return the last name. //Postcondition: The value of the data member lastName // is returned. personType(string first = "", string last =""); //constructor //Sets firstName and lastName according to the parameters. //The default values of the parameters are empty strings. //Postcondition: firstName = first; lastName = last private: string firstName; string lastName; }; class dateType { public: void setDate (int month, int day, int year); //Function to set date. //The data members dMonth, dDay, and dYear are set //according to the parameters. //Postcondition: dMonth = monh; dDay = day; // dYear = year int getDay() const; //Function to return the day. //Postcondition: The value of dDay is returned. int getMonth() const; //Function to return the month. //Postcondition: The value of dMonth is returned. int getYear() const; //Function to return the year. //Postcondition: The value of dYear is returned. void printDate() const; //Function to output the date in the form mm-dd-yyyy. dateType(int month = 1, int day = 1, int year = 1900); //constructor to set the date //The data members dMonth, dDay, and dYear are set //according to the parameters. //Postcondition: dMonth = month; dDay = day; // dYear = year //If no values are specified, the default values are //used to intialize the data members. private: int dMonth; //variable to store the month int dDay; //variable to store the day int dYear; //variable to store the year };
