简而言之,可以使用static、extern说明符来控制(好吧,这里很不准确,因为链接属性的详细规则比较复杂、琐碎,它不仅和static、extern有关,还和其他事情有关,在这里我只关注部分情形)。 声明说明符 -specifiers 回到本文的标题上来,static、extern、inline都是声明说明符,在声明时使用(当然不是任何声明都能用)
no, using inline code doesn't always guarantee improved performance. in some cases, the overhead of inlining the code may outweigh the benefits, especially if the function being called is complex or used in multiple places. it's important to profile your code and analyze the performance impact...

Is NULL in C++ equal to nullptr from C++11? Not at all. The following line does not even compile: cout<<is_same_v<nullptr, NULL><<endl; Can I convert nullptr to bool? Yes. But only if you direct-initialization. i.e. bool is_false{nullptr};. Else need to use static_cast. How...
void * __cdecl operator new(size_t cb, const std::nothrow_t&) // removed 'static inline' 此外,雖然編譯器不提供特定的診斷,但內嵌運算子 new 會被視為格式錯誤。 對非類別類型呼叫 'operator type()' (使用者定義的轉換):在先前版本的編譯器中,允許對非類別類型呼叫 'operator type()',但會默默...

What is the difference between a macro and a function? A macro is a sequence of instructions that is expanded inline wherever it is called in the code. A function, on the other hand, is a named block of code that can take arguments and return values. Functions are typically compiled sepa...
What is self-referential class in C++? It is a special type of class. It is basically created for linked list and tree based implementation in C++. If a class contains the data member as pointer to object of similar class, then it is called a self-referential class. ...
