位操作(Bit Operation) 位操作与逻辑操作 位操作不同于逻辑操作,逻辑操作是一种整体的操作,而位操作是针对内部数据位补码的操作。逻辑操作的世界里只有真假(零与非零),而位操作的世界里按位论真假(1和0)。运算也不相同。 数据的二进制形式表示8位二进制数据的补码 eg:打印一个32位数据的二进制...
C++ code:位操作实例(bit operation example) 某任务需要在A、B、C、D、E这五个人中物色人员去完成,但派人受限于下列条件: (1)若A去,则B跟去 (2)D,E两人中必有人去 (3)B,C两人中必有人去,但只去一人 (4)C,D两人要么都去,要么都不去 (5)若E去,则A,B都去 分析: 对于这个逻辑判断例子,得到...

例如,a=12 b=8如何让a变为8,b变为12呢?在这过程中我们也要好好体会交换过程中体现的思维方式和计算机的执行规则。话不多说,下面进入我们具体的内容: NO.1借助中间变作为中间过渡 int a=12,b=8,temp; temp = a; //将a的值赋给temp作为中间过渡,即temp=12 a = b; //将b的值赋给a,即a所分配的...

^The bitwise-exclusive-OR operator compares each bit of its first operand to the corresponding bit of its second operand. If one bit is 0 and the other bit is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. ...
The results of bitwise operation on signed integers is implementation-defined according to the ANSI C standard. For the Microsoft C compiler, bitwise operations on signed integers work the same as bitwise operations on unsigned integers. For example, -16 & 99 can be expressed in binary as...
Bitwise operators perform the given operation on each bit in the operand. Binary means the operator operates on two operands and unary means the operator operates on a single operand. Toggling a bit and leaving all other bits unchangedx = x ^ mask; (or shorthand x ^= mask;) Bits that ...
