Classification operator

Arithmetic operators Ø

 

Arithmetic Operators
+	addition
-	Subtraction
*	multiplication
/	division
%	Remainder
++	Increment
--	Decrement

Ø assignment operator

Assignment Operators
=	Equal sign
+=	Plus equal
-=	Less equal
*=	Take equal
/=	In addition to equal
%=	Is equal modulo

Ø comparison operators

Comparison Operators
==	equal
>	more than the
<	Less than
>=	greater or equal to
<=	Less than or equal
!=	not equal to

Ø logical operators　

&& Logical AND and

In case of false is false, only the two sides at the same time is true, it is true

||   logical OR or

In case of true is true, only the two sides at the same time is false, it is false

! Non-inverted logic 

false false true variable becomes true

 

note

1. The two sides must be a logical operator of type boolean values, or the result of the boolean type expression

2. The result is a boolean logical expression data

Note that logical operators short problem:

Logic: If the left is false, then the right side of logic and arithmetic operators would not

Or logic: If the left side is true, then the right side of the logic or arithmetic operators would not

 

Ø  ternary operator

format:

Data type Boolean type variable name = expression? Results 1: 2 results;

 

Ternary operator calculated:

- boolean expression evaluates true, the overall result of the ternary operator as a result, assigned to the variable.

- boolean type expression result is false, the ternary operator as a result the overall result 2, assigned to the variable.
