Chapter 11: Problem 35

A pet store sells dogs, cats, birds, and hamsters. Write a declaration for an anonymous enumerated data type that can represent the types of pets the store sells.

Short Answer

Expert verified
Answer: An anonymous enumerated data type is a user-defined data type without a name, consisting of a set of named values called enumerators. It is used to represent a collection of related constants. In the context of a pet store, an anonymous enum can represent pet types, such as dogs, cats, birds, and hamsters, using the following declaration: ```c enum { DOGS, CATS, BIRDS, HAMSTERS }; ``` By default, the first enumerator has the value 0, and each subsequent enumerator's value is one more than its predecessor. In this case, DOGS would have the value 0, CATS would have the value 1, BIRDS would have the value 2, and HAMSTERS would have the value 3.

Step by step solution

01

Understand Enumerated Data Types

Enumerated data types (enums) are user-defined data types that consist of a set of named values, called enumerators. Enums are useful for representing a collection of related constants, such as the types of pets in this exercise.
02

Declare an Anonymous Enumerated Data Type

An anonymous enumerated data type does not have a name, which means it can't be reused. To declare an anonymous enumerated data type, you use the "enum" keyword followed by the list of possible values enclosed in curly braces{}. In this case, the possible values are dogs, cats, birds, and hamsters: ```c enum { DOGS, CATS, BIRDS, HAMSTERS }; ```
03

Understand How Enumerators Are Assigned Values

By default, the first enumerator in an enum has the value 0, and each subsequent enumerator's value is one more than the value of its predecessor. In this example, DOGS would have the value 0, CATS would have the value 1, BIRDS would have the value 2, and HAMSTERS would have the value 3. However, you can also explicitly set the values of the enumerators if necessary. For example: ```c enum { DOGS = 0, CATS = 1, BIRDS = 2, HAMSTERS = 3 }; ``` This would achieve the same result as the default assigned values for this exercise.
