This article introduces the knowledge of "how to use the bit operator in C language". In the operation of practical cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Bit operator analysis

Bit operator in C language

The bit operator operates directly on the bit bit, which is the most efficient.

& bitwise and | bitwise or ^ bitwise XOR ~ reverse right shift

Move to the left and to the right

The left Operand must be of integer type

Shift operation after char and short are implicitly converted to int

The range of the right Operand must be: [0recom 31]

The left shift operator > shifts the binary bit of the Operand to the right

Rule: high position complement symbol bit, low position discard

The following code:

# include int main () {printf ("% d\ n", 3 > 1); printf ("% d\ n",-1 > > 1); printf ("% d\ n", 0x01
