c language bit operators

Bitwise operators allow processing of individual bits within a byte or larger unit of data: any bit or bits can be cleared, set, or inverted. You can also shift the bit pattern of an integer to the right or left.

1. "&"

Bitwise AND operation, perform "AND" operation based on binary bits. Operation rules:

0&0=0;   
0&1=0;    
1&0=0;     
1&1=1;

2, "|"

Bitwise OR operator, perform "OR" operation based on binary bits. Operation rules:

0|0=0;   
0|1=1;   
1|0=1;    
1|1=1;

3, "^"

XOR operator, performs "XOR" operation based on binary bits. Operation rules:

0^0=0;   
0^1=1;   
1^0=1;  
1^1=0;

4, "~"

Negation operator, performs "inversion" operation based on binary bits. Operation rules:

~1=0;  
~0=1;

5, "96ef5a3f369077d16e8f68c26d34bb54>"

Binary right shift operator. Shift all the binary digits of a number to the right by a certain number of bits. Positive numbers are padded with 0s on the left, negative numbers are padded with 1s on the left, and the right sides are discarded.

A >> 2 will get 15, which is 0000 1111
