In C++03 the identifiers declared in an enum exist only in the same scope as the enum type itself. A; E::B; // error in C++03 C++11 makes it legal to qualify enum identifiers with the enum name, and also introduces enum classes, which create a new scope for the identifiers instead...
This section describes how to call an enumeration method and how to handle the data in the returned DataTable object.The EnumCollations method returns a system DataTable object. The DataTable object requires further navigation to access all available collation information about the instance of SQL ...
If I was stuck with a compiler that doesn't support C++11, I'd go with wrapping an int-type in a class that then permits only use of bitwise operators and the types from that enum to set its values: template<class ENUM,class UNDERLYING=typename std::underlying_type<ENUM>::type> class...
When to Use Enum in C Enums in C are used to define a set of named integral constants that represent a set of related values. Here are some situations where enums are commonly used: Improving Code Readability:Enums make code more readable by providing descriptive names for integral constants...
By default, the underlying type of an enumeration is int. However, you can specify the type to be signed or unsigned forms of int, short, long, __int32, or __int64. You can also use char.// mcppv2_enum_3.cpp // compile with: /clr public enum class day_char : char {sun, ...
Switch on Enum Using Traditional Switch and Case in Java In the example, we create an enum inside the SwitchEnum class and name it Days. It holds seven constants that are the days of a week. We use the switch and case method to show a different message for each day. We get the valu...
objectsin the final code emitted by the compiler. Because of this, you can use enums to make a codebase more readable, as you can have multiple constant values grouped in the same data structure, while also making the code more type-safe than just having differentconstvariables laying ...
To bind my C++ enum to Lua I can use sol::state::new_enum . This creates a read-only table with the enumeration values I supply. The problem is that such table is not iterable in Lua. I can make it iterable by implementing the __pairs or...
