int a = 10, b = 20, c = 30 // (c > b > a) is treated as ((c > b) > a), associativity // is left to right. Therefore the value becomes ((30 > 20) > // which becomes (1 > 20) 参考: Operator Precedence and Associativity in C - GeeksforGeekswww.geeksforgeeks....
Order of Evaluation, Precedence, and Associativity Order of operand evaluationisindependent of precedence and associativity. In an expression suchasf() + g() * h() +j(): • Precedence guarantees that the results of g() and h() are multiplied. • Associativity guarantees that the result o...

Associativity specifies how to group operators at the same precedence level. 结合性规定了具有相同优先级的运算符如何进行分组。 举个例子: a=b=c=d; 由于该表达式中有多个赋值运算符,到底是如何进行分组的,此时就要看赋值运算符的结合性了。因为赋值运算符是右结合性,因此该表达式等同于(a=(b=(c=d))),...
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 ...
