In above program X and Y are two static data members and print() is a static member function. According to the rule of static in C++, only static member function can access static data members. Non-static data member can never be accessed through static member functions. ...
*/ CRT_CALL_STATIC_FUNCTION (INIT_SECTION_ASM_OP, __do_global_ctors_aux) 这个宏将会展开,它将这个__do_global_ctors_aux放入.init节,然后由crti中的init遍历来完成。 init节如何遍历 这个实现位于C库中glibc-2.7\sysdeps\generic\initfini.c 这里的处理使用了脚本,这个文件同样将会生成两个文件,分别是...

Since a static method cannot access class attributes, it can be used as a utility function to perform frequently re-used tasks. We can invoke this method using the class name. Hence, it eliminates the dependency on the instances. A static method is always predictable as its behavior remain ...

library or function should not be used in new development because it will not be supported or maintained in the future. it may still work for the time being, but it may have issues, and it's likely to be removed in a future version of the library or language. what is a javascript ...
