Operator Associativity

Operator associativity specifies the order in which operations of the same precedence are performed. Left-to-right associativity means that operations are performed left to right when operators are of equal precedence. For example, the expression

p = q + r + s;

is equivalent to the expression

p = ((q + r) + s);

because the addition operator has left-to-right associativity. Conversely, the expression

w = x = y = z;

is equivalent to the expression

w = ( x = (y = z));

because the assignment operator has right-to-left associativity.
