Chapter 3: Operators

C/C++ has a rich set of operators that can be divided into the following classes: arithmetic, relational and logical, bitwise, pointer, assignment, I/O, and miscellaneous.

Arithmetic Operators

C/C++ has the following seven arithmetic operators:

Operator	Action
–	Subtraction, unary minus
+	Addition
*	Multiplication
/	Division
%	Modulus
– –	Decrement
+ +	Increment

The +, –, *, and / operators work in the expected fashion. The % operator returns the remainder of an integer division. The increment and decrement operators increase or decrease the operand by one.

These operators have the following order of precedence:

Precedence	Operators
Highest	++  – –  – (unary minus)
	*  /  %
Lowest	+  –

Operators on the same precedence level are evaluated left to right.
