In C++, bitwise operators perform operations on integer data at the individual bit-level. These operations include testing, setting, or shifting the actual bits. For example, a & b; a | b; Here is a list of 6 bitwise operators included in C++. OperatorDescription & Bitwise AND Operator |...
The bitwise operators perform bitwise-AND (&), bitwise-exclusive-OR (^), and bitwise-inclusive-OR (|) operations. Syntax AND-expression: equality-expression AND-expression&equality-expression exclusive-OR-expression: AND-expression ...
c++中的bitwise操作 1. c/c++中有6种位操作运算符:按位与、按位或、按位反、异或、左移、右移; 2. 左移和右移不能移负数个位; 3. 异或运算符是用的很多的; 4. 不要将逻辑运算和位运算混淆,如&和&&,逻辑运算符将任何非零的看做1,但结果要么是0要么是1; 5. 左移和右移相当于乘2和除2操作; 6...

In the previous lesson on bitwise operators (O.2 -- Bitwise operators), we discussed how the various bitwise operators apply logical operators to each bit within the operands. Now that we understand how they function, let’s take a look at how they’re more commonly used. Bit masks In or...
The << and >> operators will shift a number bitwise to the left or right. If you want to display, for example, the rightmost bit, you could bitwise and (&) the number with a bitmask (like 0x0001). so you would have: 12 int x = 0x1; x << 1; will result in x = 0x2. ...
