If we write some new data to a pointer or a link, then this will also be reflected in the variable to which they point.

Pointers:


              
123456

            
int a = 2;
int *pa = &a;
cout << a << endl;

*pa = 50;
cout << a;
copy

References:


              
123456

            
int a = 2;
int &ra = a;
cout << a << endl;

ra = 50;
cout << a;
copy
