Question

8.13 LAB: Warm up: Contacts

You will be building a linked list. Make sure to keep track of both the head and tail nodes.

(1) Create three files to submit.

• ContactNode.h - Class declaration
• ContactNode.cpp - Class definition
• main.cpp - main() function

(2) Build the ContactNode class per the following specifications:

• Parameterized constructor. Parameters are name followed by phone number.

• Public member functions

  • InsertAfter() (2 pts)
  • GetName() - Accessor (1 pt)
  • GetPhoneNumber - Accessor (1 pt)
  • GetNext() - Accessor (1 pt)
  • PrintContactNode()

• Private data members

  • string contactName
  • string contactPhoneNum
  • ContactNode* nextNodePtr

Ex. of PrintContactNode() output:

Name: Roxanne Hughes
Phone number: 443-555-2864

(3) In main(), prompt the user for three contacts and output the user's input. Create three ContactNodes and use the nodes to build a linked list. (2 pts)

Ex:

Person 1
Enter name:
Roxanne Hughes
Enter phone number:
443-555-2864
You entered: Roxanne Hughes, 443-555-2864

Person 2
Enter name:
Juan Alberto Jr.
Enter phone number:
410-555-9385
You entered: Juan Alberto Jr., 410-555-9385

Person 3
Enter name:
Rachel Phillips
Enter phone number:
310-555-6610
You entered: Rachel Phillips, 310-555-6610

(4) Output the linked list. (2 pts)

Ex:

CONTACT LIST
Name: Roxanne Hughes
Phone number: 443-555-2864

Name: Juan Alberto Jr.
Phone number: 410-555-9385

Name: Rachel Phillips
Phone number: 310-555-6610

main.cpp:

#include <iostream>
using namespace std;

int main() {

/* Type your code here. */

return 0;

Above is code snippet in C++ performing all the task mentioned in question.

Two different files are used. Please keep in mind they must be in same folder and should be saved with same name as mentioned in question.
