Question

In what ways are pointers similar to references?

Expert Solution

Step 1

Introduction :

Pointers are variables that hold an address to a memory location, which points to a value of the same data type. This means that a pointer can point to a certain memory location, and the value stored at that memory location can be manipulated through a pointer.

References are similar to pointers in that they refer to an object. The difference is that references have to be initialized to an object, and they cannot be changed to refer to another object. Additionally, references cannot be null and are not addressable (meaning you cannot get the address of a reference).
