What is the syntax for declaring an enum in C?

• A. enum EnumName { VALUE1, VALUE2, VALUE3 }
• B. enum { VALUE1, VALUE2, VALUE3 } EnumName
• C. EnumName = { VALUE1, VALUE2, VALUE3 };
• D. define enum EnumName { VALUE1, VALUE2, VALUE3 };

Answer: (A)

The syntax for declaring an enum in C is correctly represented by the first option: `enum EnumName { VALUE1, VALUE2, VALUE3 };`. In this declaration, `enum` is the keyword used to define an enumerated type. The `EnumName` serves as the name of the enumeration, which can be used later in code for declaring variables of that type. The braces contain the list of enumerator names, which are essentially constants that represent integral values. When the enum is declared in this way, each enumerator gets a unique integer starting from zero for the first value and increasing by one for each subsequent value. This is a commonly used method for grouping related constants together, improving code readability and maintainability. The other options do not conform to the correct syntax for declaring an enum in C. The second option attempts to place the name after the braces, which is not valid syntax. The third option incorrectly tries to assign an enum value without using the proper declaration. The fourth option incorrectly includes the term "define," which does not belong in the standard enum declaration format.
