Operators

There are several types of operators available in C/C++:

Note: this list is not exhaustive and some symbols have multiple operator definitions depending on the context, e.g. the * operator can be used for multiplication or to dereference a pointer. (Pointers/references will be covered later in the tutorial).

Arithmetic Operators

Operator	Action	Example
=	Assignment	x = y
+	Addition	c = a+b
-	Subtraction	c = a-b
*	Multiplication	c = a*b
/	Division	c = a/b
%	Modulo (remainder after division)	rem = a%b
+=	Add then assign	a += b (equivalent to a = a+b)
-=	Subtract then assign	a-=b (equivalent to a = a-b)
*=	Multiply then assign	a*=b (equivalent to a = a*b)
/=	Divide then assign	a /=b (equivalent to a = a/b)
++	Increment	a = 0; a++; (a now is 1 )
--	Decrement	a = 1; a--; (a is now 0)

Boolean Comparison Operators

Operator	Action	Example
==	Equal to	a == b
!=	Not equal to	a != b
>	Greater than	a > b
<	Less than	a < b
>=	Greater than or equal to	a >= b
<=	Less than or equal to	a <= b

Note: Boolean operator statements return zero if false and non-zero if true

Logical Operators

Operator	Action	Example
&&	And	(a == b) && (b == c)
||	Or	` (a == b)
!	Not	!(a == b)
