 Q1: Define Operators. Discuss various types of Operators in C- program?

Ans: OPERATORS:

Operators are special symbols used for specific operators' purposes.
There are seven types of operators that are used in ( C )  C++programing

1- Arithmetic Operators

2- Increment Operators

3- Decrement Operators

4- Relational Operators

5- Logical Operators

6- Assignment Operators

7- Arithmetic Assignment Operators (IDEAL COLLEGIATE)

1. ARITHMETIC OPERATORS

In arithmetic operators, five different operators are used to perform
Arithmetic operators. i,e Addition(+) ,Subtraction(-), Multiplication(*),
Division(/), Remainder/Module (%).

2. INCREMENT OPERATORS

The increment operators can be used with any type of variable 
1 to the value of a variable.i,e prefix ++a, postfix a++.
(IDEAL COLLEGIATE)

3. DECREMENT OPERATORS

The decrement operators are the same as increment operators but subtract from the value of a variable. It is represented by - i,e prefix - - a, postfix a- -(IDEAL COLLEGIATE)

4. RELATIONAL OPERATOR

The relational operators are used to test the relation between two values.

OPERATORS	MEANING	EXPRESSION
= =	Equal to	a= =b
! =	Not equal to	a ! = b
>	Greater Than	a > b
<	Less Than	a < b
>=	Greater Than Or Equal To	a  >= b
<=	Less Than Or Equal To	a <= b

5. LOGICAL OPERATORS:

                        Logical Operators are used to determine two relational expressions There are three logical operators that are used in C programming.(IDEAL COLLEGIATE)

Operators	Description	Expression
&&	This Operator is Called AND.	x=10, y=5, z=12,x>y && x<z
| |	It’s known as OR operator.	x=10, y=5, z=12 x>y | | x>z
!	This operator is called NOT	x=10, y=5, ! (x<y)

6. ASSIGNMENT OPERATORS:

The assignment operator (=) is used for assigning a variable to a value. These operators assign the value of the right-side expression to the left-side variable. such as x =10;(IDEAL COLLEGIATE)

7. ARITHMETIC ASSIGNMENT OPERATORS:

In arithmetic assignment operators, the arithmetic operator is combined with the assignment operator. The assignment operator comes to the right of an arithmetic operator. This operator is also known as a compound Assignment operator. (IDEAL COLLEGIATE)

Operators	Description
+=(Addition-assignment)	It adds the right operand to the left operand and assigns the result to the left operand. Example: a+=2 means a=a+2
-=(Subtraction-assignment)	It subtracts the right operand from the left operand and assigns the  to the left operand. Example:a-=3 means a=a-3
*=(Multiplication-assignment)	It multiplies right operand with the left operand and assigns the result to the left operand Example:a*=4 means a=a*4
/=(Division-assignment)	It divides the left operand with the right operand and assigns the result to the left operand Example:a/=4 means a=a/4
