1. Mathematical Operators
There are operators used to perform basic mathematical
operations. Addition (+), subtraction (-), diversion (/) multiplication (*) and
modulus (%) are the basic mathematical operators etc.
Example: If A=5 and B=10
Example
|
Result
|
Operator
|
A+B
|
12
|
+
|
A/B
|
2
|
/
|
A%B
|
0
|
%
|
2. Shift Operators
Shift Operators are used to shift Bits of any variable. There
are following Types of shift operators,
·
Left Shift Operator <<
·
Right Shift Operator >>
·
Unsigned Right Shift Operator >>>
Example: If A= 110101000101010
and B=1
Example
|
Result
|
Operator
|
A>>B
|
011010100010101
|
>>
|
Explain: This says that it's
defined to write a >> b when a is an unsigned int. As
you shift right, the least significant bits are removed, other bits are shifted
down, and the most significant bits become zero
3. Comma Operators
This is used to separate variable names and to
separate expressions.
Example: If int a,b,c;
Example
|
Result
|
Operator
|
a=b++, c++;
|
a = c++ will be done
|
,
|
4. Unary Operators
These are the operators which work on only one
operand. There are many unary operators, but increment ++ and decrement -- operators are most used.
For examples
·
unary minus(-)
·
increment(++)
·
decrement(- -)
·
NOT(!)
·
Addressof operstor(&)
·
sizeof()
Example: If a=3;
Example
|
Result
|
Operator
|
b = -a;
|
-3
|
-
|
b=++a
|
4
|
++ prefix
|
b=a++
c=a
|
3
4
|
++ postfix
|
5. Relational Operators
These operators establish a relationship between
operands. The relational operators are: less than (<), grater than (>),
less than or equal to (<=), greater than equal to (>=), equivalent (==)
and not equivalent (! =)
Example: If A=5 and B=4
Example
|
Result
|
Operator
|
B<A
|
true
|
<
|
B==A
|
false
|
==
|
6. Logical Operators
The logical operators are AND (&&) and OR
(||). They are used to combine two different expressions together.
Example: If A=5, B=4, C=11
Example
|
Result
|
Operator
|
B<A && C=A
|
false
|
&&
|
B<A || C=A
|
true
|
||
|
7. Bitwise Operators
Bitwise operator works on bits and perform
bit-by-bit operation.
Example: If A= 0011 1100 and B= 0000 1101
Example
|
Result
|
Operator
|
A&B
|
0000 1100
|
&
|
A|B
|
0011 1101
|
|
|
A^B
|
0011 0001
|
^
|
8. Assignment Operators
Which
can be used to assign a value to a variable.
Example: Let’s suppose variable A=8 and B=3.
Example
|
Result
|
Operator
|
A+=B or A=A+B
|
11
|
+=
|
A-=3 or A=A+3
|
5
|
-=
|
9. Ternary or Conditional Operators
The ternary if-else?
: is an operator which has three operands.
Example: Let’s suppose variable A=10
Example
|
Result
|
Operator
|
a > 5 ?
|
11
|
?
