移位操作符(shift operator) 移位操作符操作的运算对象也是二进制的“位”,但是它们只可以被用来处理整数类型(基本类型的一种)。左移位操作符(<<)能将操作符左边的运算对象向左移动操作符右侧指定的位数(在低位补0)。“有符号”右移位操作符(>>)则将操作符左边的运算对象向右移动操作符右侧指定的位数。“有符号...

If the promoted type of the left-hand operand is int, only the five lowest-order bits of the right-hand operand are used as the shift distance. It is as if the right-hand operand were subjected to a bitwise logical AND operator & (§15.22.1) with the mask value 0x1f (0b11111). ...
