base class overridden member function using the scope resolution operator (: :):

Scope resolution:As the name itself indicates,it resolves global scope to local scope
Ex:
int a=10;
int main()
{
a=20;
cout<<::a<<endl;//prints 20
return 0;
}

Useful to convey ownership of class towards a function
Ex:
class ABC{
public:
static void fun()
{
cout<<"ABC"<<endl;
}
};
class XYZ{
public:
static void fun()
{
cout<<"XYZ"<<endl;
}
};
int main()
{
ABC::fun();
XYZ::fun();
return 0;
}

It is an operator :: used mainly in class for defining the member funtions and also for accessing the global variables.

With the help of Scope Resolution operator(::) , we can define function of class outside that class.

You can tell the compiler to use the global identifier rather than the local identifier by prefixing the identifier with ::, the scope resolution operator.

:: identifier
class-name :: identifier
namespace :: identifier
Note: The identifier can be a variable or a function
