Bitwise AND Operator:& Grammar Expression & expression NoteAn expression can be another "and" expression, or (follow the type restrictions described below) equality expressions, relational expressions, addition expressions,

Bitwise operators allow you to evaluate and manipulate the bits specified in the integer number. Bitwise operators Example name result $a & $b and (bitwise AND) will set the 1 bit in the $a and $b to 1. $a | $b or (bitwise OR) sets any bit in the

Why can I use the bitwise operation of the enumeration?1. What is a bitwise operation in an enumeration?For exampleint a = 1 int b = 1 int c = 1 int d = 1 and arithmeticA | B0110--------------11 ==1+2int value = A | bNSLog (@ "%d,%d,%d,%d", Value &
