Address Book Program
Hi Everyone,
I have this final assignment and I have so many difficulties getting it done. I'm supposed to write/code an address book where I could add, delete, display and sort data. I'm not too familiar with C++ as this is my first semester taking a programming course. This is what I have ready but it wont run and I couldnt add the sorting data function. I need help please I have till 6pm. Thank you all in advance.

So I know from the compiler that there is some declaration problems that caused the program to have so many errors and never compiles. I just want some hints on how can I declare Address book? and how can I add a function that will sort my data
I notice there is a "Person" structure declared at the top of your file... is there some confusion between a "Person" and an "AddressBook"?
To get your code to at least compile, I had to do the following:
. fix the typo in the dispData() parameters "const Address Book list[]..." (there's an extra space there)
. search/replace "AddressBook" with "Person"
. add a "const int MAX_SIZE = 8;" at the top (or whatever you want the maximum number of entries to be)
. replace "numOfRecs" with "numOfContacts"
As far as sorting is concerned, do you need to implement it yourself, or are you allowed to use library functions?
(note, my rationale for replacing AddressBook with Person, was because you're passing around an array to the various functions ("AddressBook list[]"), rather than declaring a std::list<Person> or something and passing a single instance of that).

THANK YOU SO MUCH @mmay
It finally compiles. for sorting it could be either by last name or first name or even both so I dont really know if that means using library functions or come up with my own.

@Nawaf: glad to hear you've taken a step forward (^_^)d.
The question about sorting was more aimed at your assignment goals - are you _supposed_ to be implementing a sort routine yourself, or is the "address book stuff" the more important goal?
You could, for instance, ensure that the person array is always kept in sorted order, by adding some extra code to addData() such that instead of always adding the new entries on the end ("list[size++] = tmp"), you find the "right place" to put the new entry, shift all the other entries down one slot, and place the new data in the right location. This would not help for "user sorting" though, which would require some more user input (like "sort by which column?", "sort descending/ascending?").

Hey,
I tried pretty hard but im frustrated now. I could not get the code to delete/edit/sort data. Help me please. I have only 45 minutes to get that done. Thank you

Here is what I have but it is not working because apparently I added more stuff that are not declared.
