C语言中的运算符号优先级和运算顺序

表中内容第一列运算符 第二列运算顺序 从上往下依次递减优先级

如下表所示：

() [] -> .                                                                               左至右

! ~ ++ -- + - * (type) sizeof                                              右至左

* / %                                                                                   左至右

+ -                                                                                       左至右

<< >>                                                                                 左至右

< <= > >=                                                                          左至右

== !=                                                                                  左至右

&                                                                                         左至右

^                                                                                          左至右

|                                                                                          左至右

&&                                                                                      左至右

||                                                                                          左至右

?:                                                                                         左至右

= += -= *= /= %= &= ^= |= <<= >>=                                右至左

,                                                                                            右至左
