C-language bit arithmetic

In computer programs, bits of data are the smallest units of data that can be manipulated, and in theory, "bitwise operations" can be used to complete all operations and operations. The general bit operation is used to control the hardware, or to do the data transformation use, but the flexible bit operation can effectively improve the efficiency of the program operation. The C language provides the function of bit arithmetic, which makes C language can also be used to write system program like assembly language.

The bitwise operator C language provides six bitwise operators:

& Bitwise AND

| Bitwise OR

^ Bitwise XOR OR

~ Take counter

<< left Shift

>> Right Shift
