What is a scope operator?

What is a scope operator?

its the 2 colons next to each other. when you define a class member function its like this:

Code:

---

void myclass::myfunction( )
{
blah;
blah;
blah;
}

---

the :: indicates that myfunction is limited to being used by instances of myclass.

Also if you have a global and local identifier it can be used to distinguish them:

Code:

---

int var = 10;

void main( )
{
    int var = 20;
    cout << "global variable = "  << ::var << endl;    //prints 10
    cout << "local variable = " << var << endl;        //prints 20
}

---

Hope that helps....

Also, you can access member functions of a class without declaring an object of that class (Like ios::binary), provided they're declared as static of course.
