The Scope Resolution Operator

  
#include <iostream>

using namespace std;

int main()
{                                            
   int count1 = 10;
   int count3 = 50;
   cout << "Value of outer count1 = " << count1 << endl;
   cout << "Value of global count1 = " << ::count1 << endl;

      int count2 = 30;
      cout << "Value of inner count1 = " << count1 << endl;
      cout << "Value of global count1 = " << ::count1 << endl;
