Answer 1

(1) Arithmatic operator:

Operator	Meaning
+	Addition
-	Subtraction
*	multiplications
/	Division
%	Modulation

(2) Relational operator: These are used to test the relation between two values.

<=	Is Greater than or equal to
==	Is equal to

(3) Increment operator or Decrement operator =
C++ has too unary operator called increment or
decrement operator these adding or subtracting one from
operand.
Ex:  + + m  or  m + +    
= – – m  or  m – –
if     m = 5
then    m + + ⇒ 5 + + ⇒ 6
or          
5 – – = 4
(4) Assignement operator (=)
Assignment (=) operator are used to assign the result of an expression. The assignment operator can be used with in any valid expression.
Syntax ⇒ Variable name = Expression
Ex: = x = a 
(5) Insertion operator:
<< is insertion or put to operator. It inserts (or sends) the contents of the variable on its right to theobject on its left.
For example:  cout << string ;
This statement will display the contents of string. Here cout is a predefined object that represents standard output stream in C + +.
(6) Extraction operator:
The operator >> is extraction operator or get from operator. If extracts (or takes) the value from thekeyboard and assign it to the variable on its right. This is similar to scanf ( ) operation. For example  cin >> number 1 ;
