Member functions can be made static as well. Here is the above example with a static member function accessor: #include <iostream> class Something { private: static inline int s_value { 1 }; public: static int getValue() { return s_value; } // static member function }; int main() ...
This check finds non-static member functions that can be made static because the functions don’t use this. This check also triggers readability-static-accessed-through -instance check as we are trying to access a static member function through an instance. Change-Id: Ia0867db019db8e40e710bd...
Static functions declared inside a class can be called using the member-selection operators or by specifying the fully qualified function name (including the class name). 备注 A function declared using the friend keyword is not considered a member of the class in which it is declared a friend ...
Hence, a pointer to a static function in C++ cannot be made to point to a similar member function of a class. As a result, I am led to assume that the "c_f_pointer" in interoperability refers strictly to C-static functions. In fact, a quick test confirme...
The idea of using the this pointer in a static function as it is used now is also not a good idea.I would recommend redesigning the class so that the function can be made non-static.«_Superman_» Microsoft MVP (Visual C++)
The low bit of a function pointer to a non-static member function is never set. On most platforms, this is either always true or can be made true at little cost. For example, on platforms where a function pointer is just the address of the first instruction in the function, the impleme...

We already know what member functions are and what they do. Now lets study some special member functions present in the class. Simple function in C++, Inline function in C++, Friend function in C++ etc
Note that static local variables_idhas kept its value across multiple function calls. Class types bring two more uses for thestatickeyword: static member variables, and static member functions. Fortunately, these uses are fairly straightforward. We’ll talk about static member variables in this less...
