Question

Hello I need some help with my CC+ project.

My current project erasing the first two phone numbers and only printing the 3rd phone number out in the list. Any idea on how to correct.

Here is the error.

Person 1 Enter name: Enter phone number You entered: Roxanne Hughes Person 2 Enter name: Enter phone number You entered: Juan Alberto Jr Your output starts with Person 3 Enter name: Enter phone number You entered: Rachel Phillips 310- CONTACT LIST Contact Name: Person 1 Enter name: Enter phone number: You entered: Roxanne Hughes 443-555-2864 Person 2 Enter name: Expected output starts with Enter phone number You entered: Juan Alberto Jr., 410-555-9385

}

Here is the full assignment details if there is any futher questions

This program needs to be completed in C++.

(1) Create three files to submit.

Contacts.h - Class declaration

Contacts.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: 310-555-661

C++:

main.cpp:

#include <iostream>
#include "Contacts.h"
using namespace std;
int main()
{
ContactNode *List,*head;
string Name;
string PhoneNum;
List=new ContactNode;
for(int i=0;i<3;i++){
cout<<"Person " <<i+1<<endl;
cout<<"Enter name: "<<endl ;
getline(cin, Name);
cout<<"Enter phone number: "<<endl ;
getline(cin, PhoneNum);
cout<<"You entered: "<<Name<<", "<< PhoneNum<<endl<<endl ;
List->InsertAfter(new ContactNode(Name,PhoneNum));
}
cout<<endl<<endl<<"CONTACT LIST"<<endl<<endl;
List->PrintContactNode();
return 0;
}

Contacts.cpp:

#include <iostream>
#include "Contacts.h"
using namespace std;

ContactNode::ContactNode(){
nextNodePtr=NULL;
}

ContactNode::ContactNode(string name, string phoneNum){
contactName=name;
contactPhoneNum=phoneNum;
nextNodePtr=NULL;
}
void ContactNode::InsertAfter(ContactNode *nextNode){
ContactNode *temp;
if(nextNodePtr==NULL)
nextNodePtr=nextNode;
else{
temp=nextNodePtr;
while(temp->nextNodePtr!=NULL){
temp=temp->GetNext();
}
temp->nextNodePtr=nextNode;   
}
}
string ContactNode::GetName(){
return contactName;
}
string ContactNode::GetPhoneNumber(){
return contactPhoneNum;
}
ContactNode* ContactNode::GetNext(){
return nextNodePtr;
}
void ContactNode::PrintContactNode(){
ContactNode *temp;
  
if(nextNodePtr!=NULL) {
cout<<"Contact Name: "<<nextNodePtr->GetName()<<endl;
cout<<"Phone number: "<<nextNodePtr->GetPhoneNumber()<<endl<<endl;
  
GetNext()->PrintContactNode();
}
}

Contacts.h:

#ifndef Contact_H
#define Contact_H
#include<string>
using namespace std;
class ContactNode{
public:
ContactNode();
ContactNode(string name, string phone);
void InsertAfter(ContactNode*);
string GetName();
string GetPhoneNumber();
ContactNode* GetNext();
void PrintContactNode();
private:
string contactName;
string contactPhoneNum;
ContactNode* nextNodePtr;
};
#endif

OUTPUT:
