c++ operators

Operator	Description	Example
Arithmetic Operators
=	Assignment	x=3; assigns 3 to x.
+	Addition of numbers, concatenation of Strings	1+2 gives 3, “hel”+”lo” gives “hello”
+=	Add and assign numbers, concatenate and assign Strings	x+=1; same as x=x+1;
–	Subtraction	2-1 gives 1
-=	Subtract and assign	x-=1; same as x=x-1;
*	Multiplication	2*3 gives 6
*=	Multiply and assign	x=2; same as x=x2;
/	Division	10/2 gives 5
/=	Divide and assign	x/=2; same as x=x/2;
%	Take remainder	10%3 gives 1
%=	Take remainder and assign	x%=3; same as x=x%3;
++	Increment by one	x++; same as x=x+1;
—	Decrement by one	x–; same as x=x-1;
Comparison Operators
>	Greater than	3>2 gives true
>=	Greater than or equal to	3>=2 gives true, 2>=2 gives true
<	Less than	2<3 gives true
<=	Less than or equal to	2<3 gives true, 2<=3 gives true
!=	Not equal to	2!=3 gives true
==	Boolean equals	3==3 gives true
Logical Operators
!	Boolean NOT	!true gives false
&&	Boolean AND	true&&true gives true, true&&false gives false
\|\|	Boolean OR	true\|\|true gives true, true\|\|false gives true
Bitwise Operators
~	Bitwise NOT	~10001001 gives 01110110
\|	Bitwise OR	01010000 \| 11001111 gives 11011111
\|=	Bitwise OR and assign	x\|=10001000; same as x=x\|10001000;
^	Bitwise XOR	11000011 ^ 11010001 gives 00010010
^=	Bitwise XOR and assign	x^11001100; same as x=x^11001100;
&	Bitwise AND	11001111&01010000 gives 01000000
&=	Bitwise AND and assign	x&=11001111; same as x=x&11001111;
>>	Shift bits right	10000100>>2 gives 100001
>>=	Shift bits right and assign	x>>=2; same as x=x>>2
<<	Shift bits left	11110000<<2 gives 11000000
<<=	Shift bits left and assign	x<<=2; same as x=<<2;
>>>	Unsigned bit shift right	10000100>>2 gives 00100001
>>>=	Unsigned bit shift right and assign	x>>>=2; same as x=x>>>2
Other Operators
?:	Ternary	max=(a>b) ? a : b; if a>b take a, else take b
