Short Note on Scope Resolution Operator in c++

                                                                      This operator can be used in situations where a global variable exist with the same name as a local variable.

#include <stdio.h>

int  xyz=50;  // global variable

int main ()

{

              for(register int xyz=1;xyz<10;xyz++)

               // Here xyz is local variable

{

      printf(“%d,::xyz/xyz”); //local variable

}

returnno();

}

In this code fragment the scope resolution operator is used to address a global variable instead of the local variable with the same name.
