Hi everyone,
I'm just trying to get this address book to sort the names alphabetic lly but I could not figure it out. I know I will add an extra case with a unique letter but where do I define the function? One more thing, my code is having some sort of a problem reading items from the disk why? what can I do to make it work properly? here is my code
#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;
}
