Exercise 1.9

Write a program that uses a while to sum the numbers from 50 to 100.

Exercise 1.10

In addition to the ++ operator that adds 1 to its operand, there is a decrement operator (--) that subtracts 1. Use the decrement operator to write a while that prints the numbers from ten down to zero.

§ 2.6.2 (p. 76)

Exercise 2.41

Use your Sales_data class to rewrite the exercises in § 1.5.1 (p. 22), § 1.5.2 (p. 24), and § 1.6 (p. 25). For now, you should define your Sales_data class in the same file as your main function.

§ 1.5.1 (p. 22)

Exercise 1.20

http://www.informit.com/title/0321714113 contains a copy of Sales_item.h in the Chapter 1 code directory. Copy that file to your working directory. Use it to write a program that reads a set of book sales transactions, writing each transaction to the standard output.

Write a program that reads two Sales_item objects that have the same ISBN and produces their sum.

§ 1.5.2 (p. 24)

Exercise 1.23

Write a program that reads several transactions and counts how many transactions occur for each ISBN.

Exercise 1.24

Test the previous program by giving multiple transactions representing multiple ISBNs. The records for each ISBN should be grouped together.
