WebUsing scoped enums for bit flags in C++. 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.

"WebA bit wise XOR (exclusive or) operates on the bit level and uses the following Boolean truth table: true OR true = false true OR false = true false OR false = false. Notice that with an XOR operation true OR true = false where as with operations true AND/OR true = true, hence the exclusive nature of the XOR operation. " - Bool bitwise c++
