C Programming for beginners, operators used in C

Operators used in C

x=0; y=10; z=20;

Operator	Usage	Example	Result
Arithmatic Operators
+	Addition of variables	x = y + z	x=30
-	Subtraction of variables alter variables +/- sign	x = y-z x = -y	x=-10 x= -20
*	Multiplication of variables	x = y*z	x=200
/	Division of variables	x = y/z where z>0	x=0 (integer) x=0.500000(float)
%	Modulus Operator	x = y%z	x=10
++	Increment Operator increase variable value by 1	x++	x=1
--	Decrement Operator decrease variable value by 1	x--	x=-1
Comparison/Relational Operators
==	Logical Equals to	x==y	FALSE or 0
!=	Not Equal to	x!=y	TRUE or 1
>	Greater Than	z>y x>y	TRUE or 1 FALSE or 0
<	Less Than	z<y x<y	FALSE or 0 TRUE or 1
>=	Greater Than or Equals to	z=10 z>=y x>=y	TRUE or 1 FALSE or 0
<=	Less Than or Equals to	y=0 z<=y x<=y	FALSE or 0 TRUE or 1
Logical Operators
!	Logical NOT variable value zero than it returns 1 else returns 0(Zero)	!x !y	1 0
&&	Logical AND returns 1 when both the values are same else returns 0(Zero)	0 && 0 0 && 1 1 && 0 1 && 1	0 0 0 1
||	Logical OR returns 0(Zero) when both the values are 0(Zero) else returns 1	0 && 0 0 && 1 1 && 0 1 && 1	0 1 1 1
Bitwise Operators
~	Bitwise NOT	x becomes binary 0000, so ~x  in bitwise 1111... y=8 becomes binary 1000, so ~y becomes ...1110111	-1 -9
&	Bitwise AND	x=5, y=6 z=x&y x-0101 y-0110 ----------- z-0100	4
|	Bitwise OR	x=5, y=6 z=x&y x-0101 y-0110 ----------- z- 0111	7
