2. Logical operators
3. Increment and Decrement operators
4. Assignment operators
5. Conditional operator
6. Bitwise operators

Arithmetic Operators :

Operator	Meaning	Example	Result
+	addition	5+2	7
-	subtraction	5-2	3
*	multiplication	5x2	10
/	division	5/2	2
%	modulus operator to get remainder in integer division	5 % 2	1

Relational Operators :

Operator	Meaning	Example	Result
<	less than	5<2	false
>	greater than	5>2	true
<=	less than or equal to	5<=2	false
>=	greater than or equal to	5>=2	true
==	equal to	5==2	false
!=	not equal to	5!==2	true

Logical Operators :

Operator	Meaning	Example	Result
&&	logical and	(5<2)&&(5>3)	false
||	logical or	(5<2)||(5>3)	true
!	logical not (negation)	!(5<2)	true

Note : logical not(!) is unary operator which requires only one operand (true to false and vice versa).

Increment and Decrement operators :

Increment operator (++) is used to increase the value of an integer or char variable.
Decrement operator (--) is used to reduce the value of an integer or char variable.

Examples :

m = 15;
m++ or ++m will produce the result m = 16.

m = 15;
m-- or --m will produce the result m = 14.

Note : That m++ and m-- are referring the post-fix increment and decrement operation, and ++m and --m are referring the prefix increment and decrement operation.

Assignment Operators :

Operator	Meaning	Example	Result
+=	m += 10	m = m + 10	25
-=	m -= 10	m = m - 10	5
*=	m *= 10	m = m * 10	150
/=	m /= 10	m = m / 10	1
%=	m %= 10	m = m % 10	5

Conditional Operators :

Conditional operator is used to check a condition and select a value depending on the condition. Normally the selected value will be assigned to a variable which ha the following form.

variable = (condition) ? value 1 : value 2;
When this operator is execute by the computer, the value of the condition is evaluated. If it is true then value 1 is assigned to the variable, otherwise value 2 is assigned to the variable. Consider the following example.

big = ( a > b ) ? a : b
In this operation, the computer checks the value of the condition (a>b); If it is true a is assigned to big; otherwise b is big.

Conditional operator, like assignment operators, is also more concise and more efficient.

Bitwise Operators :

Operator	Meaning
<<	shifts the bits to left
>>	shifts the bits to right
~	bitwise inversion (one's complement)
&	bitwise logical and
|	bitwise logical or
^	bitwise exclusive or
