It can be accessed by any member function of the class. Normally, it is accessed with the class scope operator. If it is private, use a static member function to read or write it.
For the static variables, we have to initialize them after defining the class. To initialize we have to use the class name then scope resolution operator (::), then the variable name. Now we can assign some value. The following code will illustrate the of static member initializing technique.
Static Member Functions in C++ To create a static member function we need to use the static keyword while declaring the function. Since static member variables are class properties and not object properties, to access them we need to use the class name instead of the object name.
When the member variables are declared with a static keyword in a class, then it is known as static member variables. They can be accessed by all the instances of a class, not with a specific instance. The member function of a class declared with a static keyword is known as a static method.
I've got a static class member which is some container, like
(Foo.h)
class Foo
{
...
private:
static list<string> s_List;
}
I need to populate the list with a number of specific values. Actually it should be also const, but that might overcomplicate the problem further. All the class member functions are static, so initializing it in a constructor doesn't make sense.
