1.3.4.Using the unary scope resolution operator

#include <iostream>

using std::cout;

using std::endl;



int n = 7; 



int main()

{

   double n = 10.5;



   cout << "Local double value of n = " << n

      << "\nGlobal int value of n = " << ::n << endl;

   return 0;

}

Local double value of n = 10.5
Global int value of n = 7
