Associativity
Associativity is one of those subjects that is poorly explained in most programming texts. In fact, a good way to judge a programming text for any language is to look for its explanation of associativity. Silence is not golden.
There are three factors that determine the ultimate value of an expression in any algorithmic language, and they work in this order: precedence, associativity, and order of evaluation.
Precedence says that some operations bind more tightly than others. Precedence tells us that the multiplication in a + b * c will be done before the addition, i.e., we have a + (b * c) rather than (a + b) * c. Precedence tells us how to bind operands in an expression that contains different operators.
Associativity is ...
