在C++memory model中对static local variable,说道:The initialization of such a variable is defined to occur the first time control passes through its declaration; for multiple threads calling the function, this means there’s the potential for a race condition to define first. 局部静态变量不仅只会...
classPoint{public:voidinit(){}staticvoidoutput(){}};voidmain(){Point::init();Point::output();} 报错: 'Point::init':illegal call of non-staticmemberfunction 结论1:不能通过类名来调用类的非静态成员函数。 通过类的对象调用静态成员函数和非静态成员函数。

Most of the time the compiler must deal withdynamicvariables, i.e. variables that are initialized and destroyed at runtime: local (block-scope) variables, function arguments, non-static class members, etc. The compiler has little chance to initialize such variables before execution starts: How ...
