An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations.
Arithmetic Operators Relational Operators Logical Operators Bitwise Operators Assignment Operators
Examples with A = 35 and B = 15
Arithmetic Operators
+ Add (A + B) = 50
- Subtract (A - B) = 20
* Multiply (A * B) = 525
/ Divide (A / B) = 2
% Modulus (A % B) = 5
Relational Operators
== Equality check (A == B) is not true
!= Inequality check (A != B) is true
> Greater than check (A > B) is true
< Less than check (A < B) is not true
>= Greater than or equal (A >= B) is true
<= Less than or equal (A <= B) is not true
Logical Operators(assume A = true, B = false)
&& Logical AND (A && B) is false
|| Logical OR (A || B) is true
! Logical NOT !(A && B) is true
Bitwise Operators
Bitwise operator works on bits and performs bit by bit operation.
a b a & b a | b a ^ b
0 0 0 0 0
0 1 0 1 1
1 1 1 1 0
1 0 0 1 1
Assume if A = 60; and B = 13; now in binary format, they will be as follows ?
A = 0011 1100
B = 0000 1101
-----------------------
A&B = 0000 1100
A|B = 0011 1101
A^B = 0011 0001
~A = 1100 0011
Assignment Operators
= Simple assignment C = A + B
+= Add AND assignment C += A (same as C = C + A )
-= Subtract AND assignment C -= A (same as C = C - A )
*= Multiply AND assignment C *= A (same as C = C * A )
/= Divide AND assignment C /= A (same as C = C / A )
%= Modulus AND assignment C %= A (same as C = C % A )
<<= Left shift AND assignment C <<= 2 (same as C = C << 2)
>>= Right shift AND assignment C >>= 2 (same as C = C >> 2)
&= Bitwise AND assignment C &= 2 (same as C = C & 2 )
^= bitwise exclusive OR and assignment C ^= 2 (same as C = C ^ 2)
|= bitwise inclusive OR and assignment C |= 2 (same as C = C | 2)
