• The type of result does not depend upon the type of operands. The
result of a logical operation is either true (1) or false (0).
• Operator ‘%’(modulo) is used only for integer operands.
• Bitwise operators are used only for integer operands.
5.4 Expressions
Expressions are sequences of operators and operands that are used for one or more of
these purposes:
• Computing a value from the operands.
• Designating objects or functions.
• Generating “side effects.” (Side effects are any actions other than the
evaluation of the expression — for example, modifying the value of an
object.)
5.4.1 Types of Expressions
MAXL expressions are divided into several categories:
• Primary expressions . These are the building blocks from which all other
expressions are formed.
• Postfix expressions . These are primary expressions followed by an operator
— for example, the array subscript or postfix increment operator.
• Expressions formed with unary operators . Unary operators act on only one
operand in an expression.
• Expressions formed with binary operators . Binary operators act on two
operands in an expression.
• Logical Operators . Used to combine multiple conditions formed using
relational or equality expressions.
• Simple Assignment .
5.4.1.1 MAXL Primary Expressions
Primary expressions are the building blocks of more complex expressions. They are
literals and names.
Syntax
primary-expression:
literal
( expression )
name
A literal is a constant primary expression. Its type depends on the form of its
specification. See
Literals for complete information about specifying literals.
