~ the NOT Operator (非运算符) | the OR Operator (或运算符) & the AND Operator (与运算符) ^ the XOR Operator (异或运算符) ~ the NOT Operator(非运算符) 以下是《Thinking in java》中的描述: The bitwise NOT (~, also called the ones complement operator) is a unary operator; it takes...
按位“非”(~ ,也称为取补运 算,ones compliement operator )属于一元操作符;它只对一个操作数进行操作(其他位操 作是二元运算)。按位“非”生成与输入位相反的值——若输入 0,则输出 1;输入 1,则输 出 0。 位操作符和逻辑操作符都使用了同样的符号。因此,我们能方便地记住它们的含义:由于“位” ...
sets: a union operation dicts: an update operation counters: a union (of multisets) operation numbers: a bitwise OR, binary operation In most cases, it is related to the | operator. See examples below. 1 Sets2 Dictionaries3 Counters4 Numbers ...
The bitwise ^ operator performs a bitwise exclusive OR operation. The bitwise | operator performs a bitwise inclusive OR operation. The following program, BitDemo, uses the bitwise AND operator to print the number "2" to standard output. class BitDemo { public static void main(String[] args)...
@Test public void givenTwoIntegers_whenOrOperator_thenNewDecimalNumber() { int value1 = 6; int value2 = 5; int result = value1 | value2; assertEquals(7, result); } Let’s see the binary representation of this operation: 0110 0101 --- 0111 Here, we can see that using OR, 0 and...

| Bitwise OR ^ Bitwise XOR ~ Bitwise complement Shift left >> Shift right Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the...
Where '|' denotes the bitwise OR operator. Input The first line of the input contains an integer T (T <= 100) which means the number of test cases. For each case, there are two integers X and K (1 <= X, K <= 2000000000) in one line. ...
The &^ operator is bit clear (AND NOT): in the expression z = x &^ y, each bit of z is 0 if the corresponding bit of y is 1; otherwise it equals the corresponding bit of x. 即z = x &^ y运算相当于先把y取反(针对y的每个...
Bitwise operator in C/C++ 歡迎來到二進位的世界。電腦資料都是以二進位儲存,想當然程式語言的變數也都是以二進位儲存。在 C/C++ 當中有幾個位元運算子: << SHIFT LEFT 、 >> SHIFT RIGHT 、 & AND 、 | OR 、 ^ XOR 、 ~ NOT ,可以對變數進行位元運算。接下來要介紹位元運算的一些用途。 &l... ...
