1. C语言中的位操作符 因为C语言的设计目的是取代汇编语言,所以它必须支持汇编语言所具有的运算能力,所以C语言支持全部的位操作符(Bitwise Operators)。位操作是对字节或字中的位(bit)进行测试、置位或移位处理,在对微处理器的编程中,特别适合对寄存器、I/O端口进行操作。因而本节将对此作比较详细地介绍。 6种...

The C bitwise operators are described below:展开表 Operator Description & The bitwise-AND operator compares each bit of its first operand to the corresponding bit of its second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is...
Bitwise Operators in C Programming In the arithmetic-logic unit (which is within the CPU), mathematical operations like: addition, subtraction, multiplication and division are done in bit-level. To perform bit-level operations in C programming, bitwise operators are used. OperatorsMeaning of operator...

Though we are calling it as a bitwise operators, it always operate on one or more bytes i.e, it will consider the whole representation of the number when applying bitwise operators. By using some techniques, we can manipulate a single bit on the whole representation of the number as we wi...
比较一个位(bit)和一个布尔值(boolean) cgccbooleanbitwise-operators 12 假设我有一组标志,编码在一个uint16_t类型的变量flags中。例如,AMAZING_FLAG = 0x02。现在,我有一个函数。这个函数需要检查我是否想要改变标志,因为如果我想要这样做,我需要写入Flash。而这是很昂贵的。因此,我想要一个检查,告诉我...
Bitwise operators let you manipulate data stored in computer’s memory. These operators are used to perform bit-level operations on operands.The most common bitwise operators are AND (&), OR (|), XOR (^), NOT (~), left shift (<<), and right shift (>>). Here the "~" operator is...
