Which is a limitation of an enum?
There’s one limitation of enum types: although enum types are classes, you cannot define a hierarchy of enums. In other words, it’s not possible for one enum type to extend another enum type.
How big can an enum be?
On an 8-bit processor, enums can be 16-bits wide. On a 32-bit processor they can be 32-bits wide or more or less. The GCC C compiler will allocate enough memory for an enum to hold any of the values that you have declared. So, if your code only uses values below 256, your enum should be 8 bits wide.
How do you find the max value of an enum?
This is slightly nitpicky but the actual maximum value of any enum is Int32. MaxValue (assuming it’s a enum derived from int ). It’s perfectly legal to cast any Int32 value to an any enum regardless of whether or not it actually declared a member with that value.
Where is enum size?
The size is four bytes because the enum is stored as an int . With only 12 values, you really only need 4 bits, but 32 bit machines process 32 bit quantities more efficiently than smaller quantities. Without enums, you might be tempted to use raw integers to represent the months.
How many elements are there in an enum list?
The intention is that there are 3 elements in the enum (FIRST, SECOND & THIRD), with the last being a placeholder that always designates the end of the list, so that if additional items are added it is not necessary to change the formula for the item count. – Peter Gibson Jan 28 ’15 at 1:31.
How to get total number of items defined in enum in C #?
You can get the total number of items defined in an enum in C# using the combination of the Enum.GetNames method and the Length property.
Are there extra elements in the type _ safe enum?
There are no extra elements in the type_safe enum ( BEGIN and SIZE) ( Cameron’s answer also has this problem.) It does not require casting for use. ( Cameron’s answer has this problem too.) The subtraction does not mess with the size of the enum class type.
How does subtraction affect the size of an enum class?
The subtraction does not mess with the size of the enum class type. It retains UglyCoder’s advantage over Cameron’s answer that enumerators can be assigned arbitrary values. A problem (shared with UglyCoder but not with Cameron) is that it makes newlines and comments significant which is unexpected.
