Rewrite the transaction-processing program you wrote for the exercises in § 7.1.2 (p. 260) to use these new functions.

§ 7.1.2 (p. 260)

Exercise 7.2

Add the combine and isbn members to the Sales_data class you wrote for the exercises in § 2.6.2 (p. 76).

§ 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.

Exercise 1.21

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.

§ 1.6 (p. 25)

Exercise 1.25

Using the Sales_item.h header from the Web site, compile and execute the bookstore program presented in this section.

Exercise 7.3

Revise your transaction-processing program from § 7.1.1 (p. 256) to use these members.

§ 7.1.1 (p. 256)

Exercise 7.1

Write a version of the transaction-processing program from § 1.6 (p. 24) using the Sales_data class you defined for the exercises in § 2.6.1 (p. 72).

§ 1.6 (p. 24)

Exercise 1.25

Using the Sales_item.h header from the Web site, compile and execute the bookstore program presented in this section.

§ 2.6.1 (p. 72)

Exercise 2.36

In the following code, determine the type of each variable and the value each variable has when the code finishes:

int a = 3, b = 4;decltype(a) c = a;decltype((b)) d = a;++c;++d;

Exercise 2.37

Assignment is an example of an expression that yields a reference type. The type is a reference to the type of the left-hand operand. That is, if i is an int, then the type of the expression i = x is int&. Using that knowledge, determine the type and value of each variable in this code:

int a = 3, b = 4;decltype(a) c = a;decltype(a = b) d = a;
