If consecutive operators in an expression have the same precedence, a rule called associativity is used to decide the order in which those operators are evaluated. An operator can be left-associative, right-associative, or non-associative.
5.8 Q3: An operator that associates from right to left is: 5.8 Q4: The expression if ( num != 65 ) cannot be replaced by: 5.8 Q5: An example of a unary operator is: Section 5.9 Confusing Equality (==) and Assignment (=) Operators.
And left-associative is the same meaning of associating from left to right, also the same meaning of left-to-right associativity.
So the ternary operator for example is right-associated because if you've got a?b?c:d:e, you expect it to resolve to a?(b?c:d):e. But the postfix ++, on the same precedence level as the '.' operator is left-to-right associated, which is why foo.bar++ works.
Operands of logical operations are considered true or false, that is non-zero or zero. Logical operators always return 1 or 0. Operands in a logical expression must be of scalar type.
(For example, addition has the associative property, therefore it does not have to be either left associative or right associative.)

This topic summarizes the rules and includes a precedence table for all operators. Association properties of operators A binary operator OP such as '+', '^' or '<=' either associates from left to right, that is, x OP y OP z means (x OP y) OP z, or from right to left...
Association determines whether operators at the same precedence level associate left to right or right to left; a - b - c is equivalent to (a - b) - c because subtraction associates left to right.
Left-associative operators are evaluated in order from left to right.
