左移运算符«(left shift) 高位左移后溢出,右边用0补 左右移位比乘除法效率高。左移用来计算乘法,n«2等效于n*2 右移运算符»(right shift) 由于数字采用补码表示,右移时,正数低位右移溢出,左边用0补;负数右移溢出后用1补 e.g. 00001010>>2 = 00000010 10001010>>3 = 11110001 右移用来计算正数的...
The bitwise shift operators move the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions that the bits in the value are to be shifted. The result is not an lvalue. Both operands have the same precedence and...
To perform bit-level operations in C programming, bitwise operators are used. OperatorsMeaning of operators & Bitwise 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...
There are two other bitwise operators you should know about, << or Left Shift and >> or Right Shift. These operations have the effect of shifting the bits in a byte (or short, int, long, etc) to the left or right. Thus, a Left Shift two places on 00001111 results in 00111100. ...
When we perform a 1 bit left shift operation on it, each individual bit is shifted to the left by 1 bit. As a result, the left-most bit is discarded, while the right-most bit remains vacant. This vacancy is replaced by a 0. Example 5: Shift Operators #include <iostream> int main...
Otherwise, if the shift amount exceeded the number of bits in the data type of expression1, all the original bits would be shifted away to give a trivial result. To ensure that each shift leaves at least one of the original bits, the shift operators use the following formula to calculate...

Bitwise and bit shift operators are used to perform bit level operations on integer (int, long, etc) and boolean data. These operators are not commonly used in real life situations. If you are interested to explore more, visitpractical applications of bitwise operations. ...
