##You must understand the difference between & and && in C language

## The difference between & and && in #c language is as follows:

&: According to bitwise AND operation,

For example: 0010&1101, the result is 0000 & is in java The bit logic operation:

eg: 2&3=2;

The analysis is as follows: The binary system of 2 is 10; the binary system of 3 is 11; after the logical &, it is 10

&& : Short-circuit AND, indicating that if both conditions are true, the subsequent logic will be executed;

For example: if(a==0&&b==0), which means if a is 0 and b is 0 time, proceed to the next step.

|| 短路或。 A||B，只有当A为假的时候才会对B进行判断。若A为真，则不继续对B进行判断。
| 逻辑或。 A|B，会对A, B都进行判断
! 逻辑非，当操作数为true时，返回false，否则返回true。
