Questions tagged [static-members]

Static member can be accessed using type qualifier, even if there is no instance of the class. They must be declared outside the class declaration:

// class declaration:
class a_class  { static int sf;  };

// field declaration:
int a_class::sf = 17;

Apart data fields, it can be static methods that have no access to the non-static fields but for that can be invoked without having the instance, also by type qualifier:

struct a_struct { static long the_function(); };
...
long v = a_struct::the_function();
