说明：

同一优先级的运算符，运算次序由结合方向所决定。

口诀：

括号成员第一; //括号运算符\[\]() 成员运算符. ->

全体单目第二; //所有的单目运算符比如++、 --、 +(正)、 -(负) 、指针运算\*、&乘除余三,加减四; //这个"余"是指取余运算即%

移位五，关系六; //移位运算符：<< >> ，关系：> < >= <= 等

等于(与)不等排第七; //即== 和!=

位与异或和位或; //这几个都是位运算: 位与(&)异或(^)位或(|)

"三分天下"八九十;

逻辑或跟与; //逻辑运算符:|| 和 &&

十二和十一; //注意顺序:优先级(||) 底于 优先级(&&)

条件高于赋值, //三目运算符优先级排到13 位只比赋值运算符和","高
