(Program) a. A bookstore summarizes its monthly transactions by keeping the following information for each book in stock:

Book identification number

Inventory balance at the beginning of the month

Number of copies received during the month

Number of copies sold during the month

Write a C++ program that accepts this data for each book and then displays the book identification number and an updated book inventory balance, using this relationship:

Your program should use a while statement with a fixed-count condition so that information on only three books is requested.

b. Compile and run the program written in Exercise 12a. Review the display your program produces and verify that the output is correct.
