Pointer Value and the Address-of Operator &
Explore how pointer variables in D store addresses of other variables using the address-of operator. Understand the relationship between pointers and their pointees, memory layout concepts, and how to initialize pointers correctly. This lesson helps you grasp key pointer operations for effective memory management in D programming.
We'll cover the following...
Values of pointers
Being variables themselves, pointers also have values. The default value of a pointer is the special value null, which means that the pointer is not pointing at any variable yet (i.e., does not provide access to any variable).
To make a pointer provide access to a variable, the value of the pointer must be set to the address of that variable. The pointer starts pointing at the variable that is at that specific address. From now on, we will call that variable the ...
