Scope in C++.

The :: operator is used within C++ to identify global variables that conflict with local variable names. Obviously it would be good programming practice to use suitable names in the first place...... 


        #include 
        
        int Counter = 1;
        
        main()     
        {
            int Counter = 1;
            
            for (int i=0; i< 10; i++)
            {
                cout << Counter << " " << ::Counter << endl;
                Counter++; 
            }
            
            return 0;
        }
