Alphabetically sorting items problem

[Nawaf]

Hi everyone,
I have this "Address Book" code. I am trying to get it to sort items alphabetically. I looked up how to do it but really did not find anything helpful. I like programming but I'm really bad at it. The program wont read items from disk either.

#include <cstdlib>
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <sstream>

using namespace std;

struct Person
{
 			string name;
 			string addr;
 			string phone;
 			string email;
				};

const int MAX_SIZE = 8; // max number of contacts

// functin prototypes
void addData(Person list[], int& size);
void dispData(const Person list[], int size); 
void saveFile(const Person list[], int size);
void openFile(Person list[], int& size);
char getMenuResponse();			 
int main(int argc, char *argv[])
{
  Person contactList[MAX_SIZE];
  int numOfRecs = 0;
  bool run = true;
  do
  {
    cout << "Address Book - " << numOfRecs << " Number of Contacts" << endl;
  	switch ( getMenuResponse() ) 
  	{
  		case 'A': addData(contactList, numOfRecs); break;
  		case 'D': dispData(contactList, numOfRecs); break;
  		case 'O': openFile(contactList, numOfRecs); break;
  		case 'S': saveFile(contactList, numOfRecs); break;
  		case 'Q': run = false; break;
  		default : cout << "That is NOT a valid choice" << endl;
  	}
  } while (run);
  cout << endl << "Program Terminated" << endl;
  
  // system("PAUSE"); // Commented out so the program exits upon request
  return EXIT_SUCCESS;
}

void addData(Person list[], int& size)
{
  Person tmp; // declare a temp contact that we will load before putting in the array
  char response;
  char str[256]; // needed for cin.getline; we are going to use a char array
  if (size < MAX_SIZE) {
    system("cls");
    cout << "Enter Contact Information" << endl << endl;
    cout << "Name: ";
    // Get up to 256 characters from the keyboard including white space.
    // Stop reading if encounter the \n first. If there's any chance of 
    // more than 256 characters you will have to clean up cin with
    // cin.ignore before the next input.
    cin.getline(str, 256, '\n'); // for char arrays; different from the other getline
    tmp.name = str;
    cout << endl;
		cout << "Address: ";
    cin.getline(str, 256, '\n');
    tmp.addr = str;
    cout << endl;
    cout << "Phone Number: ";
    cin.getline(str, 256, '\n');
    tmp.phone = str;
    cout << endl;
    cout << "E-mail Address: ";
    cin.getline(str, 256, '\n');
    tmp.email = str;
    cout << endl;
		// see if this record should be added to the array
    cout << "Add Contact to Address Book? (y/n) ";
    cin >> response;
    if (toupper(response) == 'Y') 
      list[size++] = tmp;
  } else {
    cout << "Sorry, Address Book is currently full." << endl;
    system("pause");
  }
  system("cls");
}

void dispData(const Person list[], int size)

    cout << "*************************************************************" << endl;
