How to sort a large text file alphabetically dictionary program

I am doing a dictionary program. Where i am trying to read the data from the text file and after it reads it it sorts it by the word and print the sorted list. as well as if i was to search for a word, or add a new word to the list. how should i do it.?

#include <iostream>
#include <fstream>
#include <sstream>
#include <iterator>
#include <vector>
#include <iomanip>
#include <conio.h>
#include "word.h"
using namespace std;


int parseLoadNSort()
{
 vector<word> wordInfo;
string Name;
string Definition;
string prtspeech;

ifstream readFile1("/Users/New/Desktop/wb1913_samp260.txt");
string line((istreambuf_iterator<char>(readFile1)),
    istreambuf_iterator<char>());

stringstream iss(line); cout << "iss(line)" << endl;
while(!iss.eof())
{
    for(int j=0; j<wordInfo.size()-1; j++)
     {
         for(int i=0; i<wordInfo.size()-1; i++)

          if(wordInfo[i].getName() > wordInfo[i+1].getName())
            swap(wordInfo[i].getName(), wordInfo[i+1].getName());

        getline(iss, Name,'\t'); 
        cout << "name - " << Name << endl;
        if (Name == "")
            break;
        getline(iss, prtspeech, '.'); 
        cout << "prtspeech - " << prtspeech << endl;
        getline(iss, Definition, '\n'); 
        cout << "definition - " << Definition << endl; 
                getch();
                word splitedColumns(Name, prtspeech, Definition);
                wordInfo.push_back(splitedColumns);

     }
        cout << "Info reterived from file" << endl;
getch();


return  1;
}
    int main()
{
parseLoadNSort();
}
