De la lecture du fichier en binaire de l'arbre et de l'écriture dans un fichier

Je suis en train de lire dans un arbre binaire d'un fichier nommé "Lincoln.txt" et les mettre dans mon arbre dans l'ordre alphabétique et je suis censé écrire le mot et le nombre de mot dans un fichier nommé "index.txt". Maintenant, je peux les lire sur mon arbre binaire pas de problème, mais je ne suis pas tout à fait sûr de la façon de les écrire dans le "index.txt". J'ai vérifier mon fichier après c'est fini et tout ce que je reçois sont des adresses. Pourriez-vous m'aider?

Voici mon codage:

main.cpp

#include <iostream>
#include "NodeClass.h"
#include <fstream>

using namespace std;

int main()
{
    string myString;
    BinaryTree myTree("");
    ifstream infile;

    infile.open("Lincoln.txt");

    while(infile)
    {
        infile >> myString;
        myTree.insert(myString, myTree.root);
    }

    ofstream outFile;

    outFile.open("index.txt");

    myTree.print(myTree.root, outFile);

    outFile.close();
}

NodeClass.cpp

#include <iostream>
#include "NodeClass.h"

using namespace std;

void BinaryTree::insert(ElementType data, TreeNode *&tree)
{
    if (tree == NULL)
    {
        tree = new TreeNode(data);
    }
    else if(data < tree->data)
        insert(data, tree->left);
    else if(data > tree->data)
        insert(data, tree->right);
    else if(data == tree->data)
        tree->count++;

}

void BinaryTree::display(TreeNode *tree, ostream& out)
{
    if (tree != NULL)
    {
        display(tree->left, out);
        out << tree->data<<" ";
        display(tree->right, out);
    }
}

void BinaryTree::print(TreeNode *tree, ofstream& outFile)
{

    if (tree != NULL)
    {
        outFile << tree->left;
        outFile << tree->data << " " << tree->count;
        outFile << tree->right;
    }

}

NodeClass.h

#include <iostream>
#include <string>
#include <fstream>
#include <fstream>

using namespace std;

#ifndef TREENODE_H
#define TREENODE_H

typedef std::string ElementType;

class BinaryTree
{
public:
    class TreeNode
    {
    public:
        ElementType data;
        int count;
        TreeNode *left;
        TreeNode *right;
        TreeNode(ElementType new_data)
            { data = new_data; left = NULL; right = NULL;};     
    };
TreeNode *root;
BinaryTree(ElementType root_data)
    { root = new TreeNode(root_data); };
~BinaryTree() { delete root;};
void insert(ElementType data, TreeNode *&tree);
void display(TreeNode *tree, ostream& out);
void print(TreeNode *tree, ofstream& outFile);
};

#endif TREENODE_H

 The Gettysburg Address



                Gettysburg, Pennsylvania

               November 19, 1863 





Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in

Liberty, and dedicated to the proposition that all men are created equal. 



Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and 

so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate 

a portion of that field, as a final resting place for those who here gave their lives that that nation 

might live. It is altogether fitting and proper that we should do this. 



But, in a larger sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground. 

The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add 

or detract. The world will little note, nor long remember what we say here, but it can never forget what 

they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they 

who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great 

task remaining before us -- that from these honored dead we take increased devotion to that cause for 

which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not 

have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government 

of the people, by the people, for the people, shall not perish from the earth.
