• Display () function is used to display the values.

• Purchase () function is used to add to numbers of books in quantity.

• Sold () function is used to minus from the number of books from the quantity of book.

Create an object of BOOK. Input the values in data members of object and then display the data of object. In main () function, also use switch statement to prompt the user for choice of operations either to purchase or sell a book. Sold () function must also check the quantity available to sell.

Declare the class Time consisting of data members hours, minutes and seconds. Invoke a null constructor Time() when an object is created, the parameterized constructor Time(hrs, min, sec) to assign values for the data members and show() member function is used to display the time information in format. Finally free the resources of data objects using destructor member function
