C++算符优先级列表

最近进行了几个面试，在算符优先级这个问题上难倒了几次，真是悲催啊，好久没用C的悲剧。

特此复习一下：

Precedence	Operator	Description	Overloadable	Associativity
1	::	scope resolution	no	left to right
2	()	function call	yes	left to right
	[]	array access	yes
	->	member access	yes
	.		no
	++  --	postfix	yes
	dynamic_cast  static_cast  reinterpret_cast  const_cast	type conversion	no
	typeid	Get type information	no
3	!  not	logical negation	yes	right to left
	~  compl	bitwise negation (complement)	yes
	++  --	prefix	yes
	+  -	unary sign operations	yes
	*  &	indirection and reference	yes
	sizeof	Size (of the type) of the operand in bytes	no
	new  new[]  delete  delete[]	dynamic memory management	yes
	(type)	Cast to a given type	yes
4	->*	member pointer selector	yes	left to right
	.*	member object selector	no
5	*  /  %	arithmetic operations	yes	left to right
6	+  -
7	<<  >>	shift operations	yes	left to right

11	^  xor	bitwise XOR	yes	left to right
12	|  bitor	bitwise OR	yes	left to right
13	&&  and	logical AND	yes	left to right
14	||  or	logical OR	yes	left to right
15	?:	Ternary conditional (if-then-else)	no	right to left
