Pointers (cont)
Now that we have assigned to p the address of variable c …
- need to be able to reference the data in that memory location
Operator * is used to access the object the pointer points to
- e.g. to change the value of
c using the pointer p:
*p = 'T'; // sets the value of c to 'T'
|
The * operator is sometimes described as "dereferencing" the pointer, to access the underlying variable

![[prev]](icon/prev.gif){kind=icon}
![[next]](icon/next.gif){kind=icon}
