Logical operator & && | ||

Logical Operators:

& And: And, if false is false, only use the symbol to be true at the same time on both sides, the result is true

|Or: Or, when true is true, only use the left and right sides of the symbol to be false at the same time, the result is false

! Not: negate unary operator

^XOR: Same as false, different as true

&与&&

&: Whether the left side is true or false, the left and right are executed

&&: True on the left, execute on the right
