EXAMPLE |
RESULT |
|
& |
Logical AND |
Produce true if both operands are also true otherwise false |
True & false |
false |
|
| |
Logical OR |
Produce true if one of them operand is true, otherwise false |
True | false |
true |
|
^ |
Logical XOR (exclusive OR) |
if exactly one operand is true, then the result is true. Otherwise, the result is false |
True ^ false |
true |
|
|| |
Short-circuit OR |
Check below program |
Check below program |
– |
|
&& |
Short-circuit AND |
It will not check the second condition if the first one is false |
Check below program |
– |
|
! |
Logical unary NOT |
This sign is used for invert the result |
!true |
false |
|
&= |
AND assignment |
This is a short sign of Produce true if both operands are also true otherwise false on the same operand |
Check below program |
– |
|
|= |
OR assignment |
This is a short sign of Produce true if one of the operand is true otherwise false on the same operand |
Check below program |
– |
|
^= |
XOR assignment |
This is a short sign of produce true if exactly one operand is true, otherwise, the result is false on the same operand |
Check below program |
