    What is the scope resolution operator? Explain how does it work in c++?
    Answer:

    The :: operator links a class name with a member name in order to tell the complier what class the member belongs to. It has another use that is it can allow access to a name in an enclosing scope that is hidden by a local declaration of the same name.

    Egname.
    Eg:
    Void f()
    {
    int I;
    I=10;
    ………..
    ……..
    }
    It may do so by preceding the I with the :: as shown here
    Void f()
    {
    int I;
    :: I=10;
    ……..
    ……..
    }
