Question

Need help with c++

(1) Define the class ContactNode per the following specifications:

Private data members
- string contactName
- string contactPhoneNumber
- ContactNode* nextNodePtr
Constructor with parameters for name followed by phone number
Public member functions
- GetName() - Accessor
- GetPhoneNumber() - Accessor
- InsertAfter()
- GetNext() - Accessor
- PrintContactNode()
- Ex: If the name is Roxanne Hughes and the phone number is 443-555-2864, PrintContactNode() outputs:
- Name: Roxanne Hughes
- Phone number: 443-555-2864
(2) Define main() to read the name and phone number for three contacts and output each contact. Create three ContactNodes and use the nodes to build a linked list. (1st attached image)
(3) Output the linked list using a loop to output contacts one at a time. (2nd attached image)
Provided template:
#include <iostream>
using namespace std;

class ContactNode {
public:
/* Declare member functions here */

private:
/* Declare data members here */

};

/* Define member functions here */

int main() {
/* Type your code here. */

return 0;
}

Ex: If the input is:
Roxanne Hughes
443-555-2864
Juan Alberto Jr.
410-555-9385
Rachel Phillips
310-555-6610
the output is:
Person 1: Roxanne Hughes, 443-555-2864
Person 2: Juan Alberto Jr., 410-555-9385
Person 3: Rachel Phillips, 310-555-6610

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

Expert Solution

Step 1

Algorithm steps to solve the given problem:

Start
Initialize pointers headPtr, currPtr, and lastPtr to null.
Create a loop to take input from user for contact name and phone number.
Create a new ContactNode object and assign it to currPtr.
Check if headPtr is null.
If headPtr is null, assign currPtr to headPtr and lastPtr.
If headPtr is not null, call InsertAfter() method of lastPtr and assign currPtr to lastPtr.
Print the contact list. 8. Create a loop to print the contact list using GetNext() method of currPtr.
Output the result.
Stop.
