Overview
"Operators are functions that use a symbolic name
"perform mathematical or logical functions
"Operators
be
are predefined in C, just like they are in most other languages, and most operators tend to
combined withthe infix style
"A logical operator (sometimes called a "Booleanoperator") is an operator that returns a Boolean
result that's based on the Boolean result of one or two other expressions
"An arithmetic operator is a mathematical function that takes two operands and performs a calculation
on them
"Other operators include assignment, relational (<, >, !=), bitwise (<<, >>,~)

"A logical operator (sometimes called a "Boolean operator") is an operator that returns a Boolean
result that's based on the Boolean result of one or twoother expressions
"Assignment operators set variables equal to values
"assigns the value of the expression at its right to the variable at its left
"A relational operator willcompare variables against eachother

Arithmetic Operators in C
Operator Description Example
Adds two operands. A+B= 30
Subtracts second operand from the first. A-B=-10
Multiplies both operands. A*B= 200
Divides numerator by de-numerator. B/A= 2
% Modulus Operator and remainder of after an integer B %A=0
division.
++ Increment operator increases the integer value by one. A++ = 11
Decrement operator decreases the integer value by A-- =9
one.

Logical Operators
Operator Description Example
&& Called Logical AND operator. If both the operands are (A&& B) is false.
non-zero, then the condition becomes true.
Called Logical OR Operator. If any of the two operands (A|| B) is true.
is non-zero, then the condition becomes true.
Called Logical NOT Operator. It is used toreverse the !(A&& B) is true.
logical state of its operand. If a condition is true, then
Logical NOT operator will make it false.

Assignment Operators
Operator Description Example
Simple assignment operator C=A+B will assign the value
of A + B to C
Add ANDassignment operator. It adds the right
equivalent to C= C+
operand to the left operand and assign the result to the Ct= A is
A
left operand.
Subtract ANDassignment operator. It subtracts the
right operand from the left operand and assigns the C-=A is equivalentto C= C-A
result to the left operand.
Multiply AND assignment operator. It multiplies the
right operand with the left operand and assigns the C*=A is equivalent to C= C*
result to the left operand. A

Assignment Operators (cont'd)
Operator Description Example
Divide ANDassignment operator. It divides the left
operandwith the right operand and assigns the result C/= Ais equivalent to C=C/A
to the left operand.
%= Modulus AND assignment operator. It takes modulus
C%= A is equivalent to C= C%
using two operands and assigns the result to the left
A
operand.
<<= Left shift AND assignment operator. C<«=2 is same as C = C<«2
Right shift AND assignment operator. C>>=2 is sameas C = C>> 2
&= Bitwise AND assignment operator. C&=2 is same as C=C&2
Bitwise exclusive OR and assignment operator. C^= 2 is same as C= C^2
Bitwise inclusive OR and assignmentoperator. C=2 is same as C= C 2

Relational Operators
Operator Description Example
Checks if the values of two operands are equal or not. If yes, (A == B) is not true.
then the condition becomes true.
Checks if the values of two operands are equal or not. If the (A != B) is true.
values are not equal, then the condition becomes true.
V
Checks if the value of left operand is greater than the value of (A> B)is not true.
right operand. If yes, then the condition becomes true.
Checks if the value of left operand is less than the value of (A<B) is true.
right operand. If yes, then the condition becomes true.
Checks if the value of left operand is greater than or equal to (A >= B) is not true.
the value of right operand. If yes, then the condition
becomes true.
<= Checks if the value of left operand is less than or equal to the (A <= B) is true.
value of right operand. If yes, then the condition becomes
true.
