* * Based on first part of code, answer is straight-forward. To inner `if` statement when we check `b` condition * Actual answer: Compilation error as `else` belongs nowhere *//* Better and correct implementation of macro */#define SET_POINT(p, x, y) do { (p)->px = (x); ...

传统的编译器通常分为三个部分,前端(frontEnd),优化器(Optimizer)和后端(backEnd). 在编译过程中,前端主要负责词法和语法分析,将源代码转化为抽象语法树;优化器则是在前端的基础上,对得到的中间代码进行优化,使代码更加高效;后端则是将已经优化的中间代码转化为针对各自平台的机器代码。
, perform an explicit cast to S on the initializer list. f(S{ 1, 2 }); } 還原switch 陳述式警告 舊版編譯器中移除了某些與 switch 陳述式相關的警告;現在已還原這些警告。 編譯器現在會發出還原的警告,而與特定情況相關的警告 (包括預設的情況) 都會在包含違規情況的程式行發出,而不是在 switch ...
