![]() The following enum uses 8 bits instead of 32 bits when the -small_enum option is used. Using Enum in C Sharp In C, Keyword Enums build enumerated types of data Enums are made for developers Enums are strongly typed constants, as described. The underlying type is the first type in the following list in which all the enumerated constant values can be represented: signed char, unsigned char, short, unsigned short, int, unsigned int, long long, unsigned long long. ![]() If you use the -small_enum option, the smallest possible byte size for the enumeration type is used. The default, which is recommended, is for the underlying type to be the first type in the following list in which all the enumerated constant values can be represented: int, unsigned int, long long, unsigned long long. In strict C89 or C99 mode, the compiler allows only enumeration constants with values that will fit in "int" or "unsigned int" (32 bits).įor C++ and relaxed C89/C99, the compiler allows enumeration constants up to the largest integral type ( 64 bits). You can assign an enum to any integer AS LONG AS the integer type is larger than the size of the enum (you should get a. ![]() ![]() The size of the integer type and whether it is signed is based on the range of values of the enumerated constants. An enum type is represented by an underlying integer type. ![]()
