An enum X : int (C#) or enum class X : int (C++11) is a type that has a hidden inner field of int that can hold any value. In addition, a number of predefined constants of X are defined on the enum. It is possible to cast the enum to its integer value and vice versa. This is all true in both C# and C++11. shoprite cortlandt manor ny facebookWebNov 21, 2024 · The result is a bit-field if the left operand is a bit-field. For non-class types, the right operand is first implicitly converted to the cv-unqualified type of the left operand, and then its value is copied into the object identified by left operand. When the left operand has reference type, the assignment operator modifies the referred-to object. shoprite cortlandt manor
