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

Rewrite the variable x using the reference and the pointer in this order.

int x = 42;
int *px = &x;
int &rx = x;

  = 3;
cout<<<< endl;

=2;
cout<<;
3
2

Var allt tydligt?

Hur kan vi förbättra det?
