Operators and Punctuation

Operator Precedence

The following table gives the precedence order and association for the supported GXC operators:

Symbol in order of precedence	Type	Association
[] () .	Expression	left to right
Postfix ++ and postfix --	Unary	right to left
Prefix ++ and prefix --	Unary	right to left
sizeof + - !	Unary	right to left
(int) (real) (class)	unary cast	right to left
* / %	multiplication	left to right
+ -	additive	left to right
< > <= >=	relational	left to right
== !=	equality	left to right
&&	logical AND	left to right
\|\|	logical OR	left to right
?:	conditional	right to left
= *= /= %= += -=	simple and compound assignment	right to left
,	sequential evaluation	left to right

Punctuation Characters

Punctuation characters are used to control how the compiler processed the source code and evaluate expressions. The following table documents the punctuation characters.

Characters	Description
;	The semicolon marks the end of an expression. One expression is always completely evaluated before starting on the next expression.
{ }	Braces mark the start and end of a group of expressions that are evaluated in order. Braces are normally used to group statements that must be executes within a control structure.
( )	Parentheses control the order of evaluation in arithmetic and logical expressions such that everything inside parenthesis is evaluated before evaluating the next associated operator outside parentheses.
