Precedence and associativity are independent from order of evaluation. The standard itself doesn't specify precedence levels. They are derived from the grammar. In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and -- and assignment operators don't ...
C(C++)运算符 一下摘自:http://www.cppreference.com/operator_precedence.html The operators at the top of this list are evaluated first. Operators within a group have the same precedence. All operators have left-to-right associativity unless otherwise noted. Order of Evaluation and of Side Effect...

参考 https://en.cppreference.com/w/cpp/language/operator_precedence 在这里我简单摘要一下: 最高: 函数/方法调用:func() 数组成员下标访问:array[index] 对象成员访问:object.member、object_ptr->member 2. 次高: 星号运算符:*ptr或type* ptr 取地址运算符:&var 3. 最低 成员指针运算符:object.*membe...
↑ sizeof 的运算数不能是转换:表达式 sizeof (int) * p 无歧义地转译成 (sizeof(int)) * p ,而非 sizeof((int)*p)。 ↑ 条件运算符中部(? 与: 之间)的表达式分析为如同加括号:忽略其相对于 ?: 的优先级。 ↑ 赋值运算符的左运算数必须是一元(第 2 级非转换)表达式。此规则在文法上禁止某些表...
