In the following table, operators grouped together in a row have the same precedence. For example, the first four entries in this table (), [], ., and -> all share the same precedence. These four operators follow the rule of Left-to-Right associativity which is used as a tie breaker when two or more of these appear in the same expression. The next group of operators starting with + and ending with (type) all share the next level of precedence.

When expressions contain multiple operators, their precedence determines the order of evaluation

Expression	Effective Expression
a - b * c	a - (b * c)
a + ++b	a + (++b)
a + ++b * c	a + ((++b)*c)

Associativity

If two operators have the same precedence, their associativity determines the order of evaluation.

Expression	Associativity	Effective Expression
x / y % z	Left - to - Right	(x / y) % z
x = y = z	Right - to - Left	x = (y = z)
~++x	Right - to - Left	~(++x)

You can rely on these rules, but it is good programming practice to explicitly group elements of an expression by using parentheses.
