Operator

Description

Example

+

Adds two operands

A + B will give 30

-

Subtracts second operand from the first

A - B will give -10

*

Multiplies both operands

A * B will give 200

/

Divides numerator by de-numerator

B / A will give 2

%

Modulus Operator and remainder of after an integer division

B % A will give 0

++

Increment operator increases integer value by one

A++ will give 11

--

Decrement operator decreases integer value by one

A-- will give 9

Operator

Description

Example

==

Checks if the values of two operands are equal or not, if yes then condition becomes true.

(A == B) is not true.

!=

Checks if the values of two operands are equal or not, if values are not equal then condition becomes true.

(A != B) is true.

> 

Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.

(A > B) is not true.

< 

Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.

(A < B) is true.

>=

Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.

(A >= B) is not true.

<=

Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.

(A <= B) is true.

Operator

Description

Example

&&

Called Logical AND operator. If both the operands are non zero then condition becomes true.

(A && B) is false.

||

Called Logical OR Operator. If any of the two operands is non zero then condition becomes true.

(A || B) is true.

!

Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.

!(A && B) is true.

Operator

Description

Example

&

Binary AND Operator copies a bit to the result if it exists in both operands.

(A & B) will give 12. which is 0000 1100

|

Binary OR Operator copies a bit if it exists in either operand.

(A | B) will give 61, which is 0011 1101

^

Binary XOR Operator copies the bit if it is set in one operand but not both.

(A ^ B) will give 49, which is 0011 0001

~

Binary Ones Complement Operator is unary and has the effect of 'flipping' bits.

(~A ) will give -61, which is 1100 0011 in 2's complement due to a signed binary number.

<< 

Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand.

A << 2 will give 240, which is 1111 0000

>> 

Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand.

A >> 2 will give 15, which is 0000 1111

Operator

Description

Example

=

Simple assignment operator, Assigns values from right side operands to left side operand

C = A + B will assign value of A + B into C

+=

Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand

C += A is equivalent to C = C + A

-=

Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand

C -= A is equivalent to C = C - A

*=

Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand

C *= A is equivalent to C = C * A

/=

Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand

C /= A is equivalent to C = C / A

%=

Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand

C %= A is equivalent to C = C % A

<<=

Left shift AND assignment operator

C <<= 2 is same as C = C << 2

>>=

Right shift AND assignment operator

C >>= 2 is same as 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 assignment operator

C |= 2 is same as C = C | 2

Operator

Description

Example

sizeof()

Returns the size of a data type.

sizeof(int), will return 4.

typeof()

Returns the type of a class.

typeof(StreamReader);

&

Returns the address of an variable.

&a; will give actual address of the variable.

*

Pointer to a variable.

*a; will pointer to a variable.

? :

Conditional Expression

If Condition is true ? Then value X : Otherwise value Y

is

Determines whether an object is of a certain type.

If( Ford is Car) // checks if Ford is an object of the Car class.

as

Cast without raising an exception if the cast fails.

Object obj = new StringReader("Hello");
StringReader r = obj as StringReader;
