C++ Operator And Expression

Programming is nothing but one kinds of problem solver, which can solve different type of problem by using legal logic .for converting logic into program we use some operator.

1.      Arithmetic operators
2.      Relational operators
3.      Logical operators
4.      Increment and decrement operators
5.      Assignment operator
 

Arithmetic operators

Symbol	Name	Description	Example
+	Add	Adds two operands	A + B
-	Subtracts	Subtracts second operand from the first	A-B
*	Multiplies	Multiplies both operands	A*B
/	Divides	Divides numerator by de-numerator	A/B
%	Modulus	Modulus Operator and remainder of after an integer division	A%B

Relational operators

Symbol	Name	Description	Example
==	Equal	Checks if the values of two operands are equal or not, if yes then condition becomes true.	A==B
!=	Not Equal	Checks if the values of two operands are equal or not, if values are not equal then condition becomes true.	A!=B
>	Greater than	Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.	A>B
<	Less than	Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.	A<B
>=	Greater than or equal	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
<=	Less than or equal	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

Logical operators

Symbol	Name	Description	Example
&&	And	Called Logical AND operator. If both the operands are non-zero, then condition becomes true.	A&&B
||	Or	Called Logical OR Operator. If any of the two operands is non-zero, then condition becomes true.	A||B
!	Nor	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)

Increment and decrements operators

Symbol	Name	Description	Example
++	Increment operator	Increases integer value by one	A++
--	Decrements operator	Decreases integer value by one	A--

Assignment operator

Symbol	Name	Description	Example
=	Assignment	Simple assignment operator, Assigns values from right side operands to left side operand	C = A + B
+=	Assignment	Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand	C += A C = C + A
-=	Subtraction Assignment	Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand	C -= A C = C - A
*=	Multiplication Assignment	Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand	C *= A C = C * A
/=	Division Assignment	Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand	C /= A C = C / A
%=	Modulus Assignment	Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand	C %= A C = C % A
<<=	Left shift assignment	Left shift AND assignment operator	C <<= 2 C = C << 2
>>=	Right shift assignment	Right shift AND assignment operator	C >>= 2 C = C >> 2
&=	Bit-wise exclusive And assignmen	Bit-wise AND assignment operator	C &= 2 C = C & 2
^=	Bit-wise exclusive OR Assignment	Bit-wise exclusive OR and assignment operator	C ^= 2 C = C ^ 2
|=	Bit-wise inclusive OR Assignment	Bit-wise inclusive OR and assignment operator	C |= 2 C = C | 2
