lab $3$ pointers and operator overloading $1$ Intro and Problem

In this lab we will be creating a database for contacts to be stored. Devices having overlapping contacts is

inefficient as each device storing duplicate contacts wastes space. So$,$ in this lab all Contact information

will be stored in one place, and on each persons device will be a single ContactBook object, a class$/$struct

that you will implement, along with a Contact class$/$struct you will implement. The ContactBook object

will only hold pointers of contacts, to greatly reduce the total amount of memory used for a large

database. So now when two devices have the same contact, they will both only hold a pointer to the

same contact in memory, instead of there being two copies of the contact.

More specifically, a pointer in cpp on a $64$ bit device is only taking up $8$ bytes, where a contact might be

holding way more bytes of information. In our example, there is only two strings for a contact to make

it simpler$($name and number$),$ but it wouldn$$t be difficult to add things like email, profile picture, and

more to each contact, which would take up a lot more memory.
