Question

20.6 Lab: 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-main0 function (2) Build the ContactNode class per the following specifications Parameterized constructor. Parameters are name followed by phone number Public member functions InsertAfter0 (2 pts) GetName0 -Accessor(1 pt) GetPhoneNumber- Accessor (1 pt) GetNext0-Accessor (1 pt) PrintContactNode Private data members string contactName string contactPhoneNum ContactNode* nextNodePtr Ex. of PrintContactNode0 output: Name: Roxanne Hughes Phone number: 443-555-2864 (3) In main0, 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
