Introduction of
Operator: Operator is the symbols
that are used to perform the various operations on the operand .such as
A + b * c
It can perform the various
operation like arithmetic operations, comparison or logical operations etc..it
refer to a symbol that tells the computer to perform certain mathematical or
logical tasks on operands .Operators can be unary and Binary .Unary operators
work on on operand like – a, b++ etc Binary operators work on the operators
like a+b, a*c.
Arithmetic Operators: This is used perform the arithmetic Operators on the
operand such as +, * ,/ ,-,%

Logical
Operators .It used when we want to test
more than one condition to make decisions .The result of logical operator AND
will be true only if both conditions are true and OR will be true if one or
more conditions are true .

Assignment
Operators:-It is used to assign value to
the variable .Value can be any constant Value or evolution of an Expression .eg
a = 5;
Some
Assignment Operator are given below:

Example
|
+=
|
X+=6

*=
|
A*=12
|
/=
|
a/=11
|
-=
|
z-=3
|
%=
|
Z%=2

Relational Operators: this
Operators are used to check the relation between two operands .These are use to
compare the two different operand and then take decisions they compare such
operand is greater ,less or equal of another operand eg
A > b

Increment /Decrement Operator
: The Increment Operator increase the values of and operand by 1 and add the 1
value in current value and Decrement
decrease the value of and operand by 1 means subtract the 1 value from
current value
1. Increment (++)
2. Decrement (--)
