推荐答案

参见 C++运营商优先级 - cppreference.com [ ^ ]。



然后按照步骤逐步打破表达式优先级和替换固定表达式（不包含变量的表达式）。根据优先顺序首先插入括号通常也很有帮助。

如果你有例如

See C++ Operator Precedence - cppreference.com[^].

Then break the expression down step by step according to the precedence and replacing fixed expressions (those that did not contain variables). It is often also helpful to insert parentheses first according to the precedence.
If you have for example

a || b && c

它将是

it will be

a || (b && c)

因为你的问题看起来像是家庭作业，所以我不会给你最后的答案。即使它不是作业，你也应该自己去理解它是如何工作的。

Because your question looks like homework, I will not give you a final answer. Even if it is not homework, you should do it yourself to understand how it works.
