| **同一优先级的运算符，运算次序由结合方向所决定。 |
| 简单记就是：！ > 算术运算符 > 关系运算符 > && > |
|
| ## 优先级记忆口 |
|
| 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: |
|
| 十二和十一; //注意顺序: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 |
|
| 逗号运算级最低! //逗号运算符优先级最低 |
