No errors, but output is not right. Pointer issue possibly - c++

Question

Im reading strings from a file and inserting them into a LinkedList in alphabetical order (C++). I have made the node and list classes but something is wrong with them. I have done this in Java and it works 100% without any problems. This leads me to believe that I must have messed up with pointers somewhere. This is also only the second time I use the '->' symbol. So I may have used it erroneously somewhere. Some helpful tips are appreciated. Thanks in advance.
//NODE CLASS
#include <string>
#include <iostream>
using namespace std;
class Node {
string word;
int count;
Node* next;
public:
Node (string aWord) {
word = aWord;
count = 1;
}
Node (string aWord, Node* theNext) {
word = aWord;
next = theNext;
}
void increaseCount() {
count++;
}
string getWord() {
return word;
}
int getCount() {
return count;
}
Node* getNext() {
return next;
}
void setNext(Node* theNext) {
next = theNext;
}
};
//LIST CLASS
#include<iostream>
using namespace std;
class LinkedList {
Node* head;
public:
LinkedList() {
head = new Node(" ");
}
void insert(string word) {
Node* temp = head;
Node* previous = head;
while (temp != NULL && temp->getWord() < word) {
previous = temp;
temp = temp->getNext();
}
if (temp == NULL) {
Node* node= new Node(word);
previous-> setNext(node);
} else {
if (temp-> getWord() == word) {
temp->increaseCount();
} else if (temp->getWord() > word) {
Node* node = new Node(word, temp);
previous->setNext(node);
}
}
}
void print() {
Node* temp = head->getNext();
while (temp != NULL) {
cout<< temp;
temp=temp->getNext();
}
}
};
//MAIN
#include <iostream>
#include <iostream>
#include <fstream>
#include "Node.h"
#include "LinkedList.h"
using namespace std;
int main(int argc, const char * argv[]) {
ifstream inFile("WordsStatisticData1.txt");
if (!inFile.is_open())
cout<< "Could not open the file"<< endl;
else {
string readData;
LinkedList list = *new LinkedList(); //Probably a problem here
while (inFile >> readData) {
list.insert(readData);
inFile.close();
list.print();
}
}
}
I may be declaring things totally wrong within the main as well.
My output looks like an address '0x' with random characters.

You're printing out temp where temp is a Node*. A pointer is just the address of an object, hence why you're getting an address in your output.
Seems like you want to get the string that the Node contains. If so, you want:
cout << temp->getWord();
Another problem you have is that you close your file and print the list inside the loop, which means it'll happen right after the first word has been read. You probably mean to do this after the loop, so all of the words in the file can be read.
You also have problem with the line you marked as such. Using the new keyword will dynamically allocate an object. These objects need to be later deleted with delete. However, you dereference the dynamically allocated object (with *) and copy it, losing any reference to the dynamically allocated object - this is a classic memory leak. The dynamic allocation here is completely unnecessary. Just do:
LinkedList list;
