Question

C++ Programming Help to create Rolodex Program, In the provided skeleton Rolodex program, there is an executable application (pre-built) that you can run to understand more in depth how the user interactions are but the TODO code is what is needed. LIke:

********

This code will be allowed:

vector<PhoneRecord> ContactRecord::GetPhoneNumberList() const
{
vector<PhoneRecord> numberList;
    for (int i = 0; i < this->PhoneNumberList.size(); i++)
    {
   numberList.push_back( this->PhoneNumberList[i]);
    }

    return numberList;
}

*****************

Must have user interaction to:

1. Add new contacts

2. Edit Existing contacts

3. Remove Existing Contacts

4. List All Contacts

5. Add three phone numbers for Contacts

6. Remove Phone From Contact

7. Quit Application

Code provided in body:

1. ContactRecord.h – Each contact can have more than one phone numbers (up to 3 to be exact). The phone numbers to be stored are for HOME, WORK, or MOBILE.

2. ContactRecord.cpp – Look for all methods that have TODO markers since I don't know what to code there.

3. ContactDataManager.h – To support multiple phone numbers per contact, the ContactDataManager class is now expanded to include new methods to handle/manage the list of phone numbers per contact.

4. ContactDataManager.cpp – Look for all methods that have TODO markersince I don't know what to code there.

5. ContactDataInputManager.h – The ContactDataInputManager class drives all the user interactions which allow him/her to add, edit, remove contacts as well as their phone numbers.

6. ContactDataInputManager.cpp – Look for all methods that have TODO markersince I don't know what to code there.

7. PhoneRecord.h - No work needed, this is part of the project to better understand

8. Main.cpp - No work needed, this is part of the project to better understand

Explanation / Answer

Hi,

There are 2 things you should read first..

1. The code in question does not show all the #include lines completely ... I tried to include the needed files as needed. So the order of #include lines in each file in answer may not match the original order you have given in question. Request you to copy paste the #include lines for each of the files as you originally have.

2. For me, The ContactDataInputManager.cpp file shows error on dataLine.erase() lines in WaitForDataLine() and also in throw new exception("...") in ContactDataInputManager::ContactDataInputManager() and ContactDataInputManager::operator=() functions. So in order to test the implementation, I just commented out these lines and tested. The program works as intented after commenting out these lines. If these lines don't show any errors for you , you don't need to comment them out.

Let me know if you have any doubts. Please do rate the answer if it helped. Thank you.
