int a[10];    //private data
public: int n;
sample()
{
cout<<"Enter The No of Elements of Array  ";
cin>>n;
cout<<"Enter The Elements\n";
for(int i=0;i<n;i++)
cin>>a[i];
}
int operator [](int k)  // overloading Subscript operator
{
return(a[k]);
}
};
main()
{
sample a;
cout<<"Elements You Entered\n";
for(int i=0;i<a.n;i++)
cout<<a[i]<<"\n";       //fetching private data using object
