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. |
