Thread: Modified Address Book Using Prebuilt Classes

Suffering a setback on a project and don't know what to do. I am supposed to create a new program by modifying an address book program I created for a previous assignment. I must modify the program to use the Array Class instead of a basic array. Then, create another new program by modifying the address book program created in the previous module to use the Vector Class instead of a basic array. I also have to implement exception catching in appropriate areas that may cause errors. I should implement exception catching in at least one area of the program for each of the Array class and Vector class programs I create.

My professor didn't cover any of this in our lesson this week and I am struggling to figure it out.

Here is my previous code that needs to be modified. There are three files (Record.h, Record.cpp, and main.cpp).

Program:

Code:

/***** Record.h *****/
#ifndef RECORD_H
#define RECORD_H
#include <iostream>
using namespace std;
//Record class
class Record {
private:
  //private data member
  int recordNumber;
  string firstName;
  string lastName;
  int age;
  int telephone;
public:
  //default constructor
   Record();
  //parameterized constructor
   Record(int, string, string, int, int);
  //getter functions
  int getRecordNumber();
  string getFirstName();
  string getLastName();
  int getAge();
  int getTelephone();
  //setter functions
  void setRecordNumber(int);
  void setFirstName(string);
  void setLastName(string);
  void setAge(int);
  void setTelephone(int);
  void print();
};

#endif                          // RECORD_H

/***** Record.cpp *****/
#include <iostream>
#include <iomanip>
#include"Record.h"
using namespace std;
//default constructor
Record::Record()
{
  recordNumber = 0;
  firstName = "";
  lastName = "";
  age = 0;
  telephone = 0;
}

//parameterized constructor
Record::Record(int rno, string fn, string ln, int ag, int tno)
{
  recordNumber = rno;
  firstName = fn;
  lastName = ln;
  age = ag;
  telephone = tno;
}

//getter functions
int Record::getRecordNumber()   //returns the recordNumber
{
  return recordNumber;
}

string Record::getFirstName()   //returns the firstname
{
  return firstName;
}

string Record::getLastName()    //returns the lastname
{
  return lastName;
}

int Record::getAge()            //returns the age
{
  return age;
}

int Record::getTelephone()      //returns the telephone
{
  return telephone;
}

//setter functions
void Record::setRecordNumber(int rno) //set the recordNumber
{
  recordNumber = rno;
}

void Record::setFirstName(string fn)  //set the firstname
{
  firstName = fn;
}

void Record::setLastName(string ln) //set the lastname
{
  lastName = ln;
}

void Record::setAge(int ag)     //set the age
{
  age = ag;
}

void Record::setTelephone(int tno)  //  //set the telephone
{
  telephone = tno;
}

void Record::print()            //print a record
{
  cout << left << setw(14) << recordNumber;
  cout << left << setw(10) << firstName;
  cout << left << setw(10) << lastName;
  cout << left << setw(5) << age;
  cout << telephone << endl;
}

/***** main.cpp *****/
#include <iostream>
#include"Record.h"
using namespace std;
//main function
int main()
{
  //array of Record
  Record rec[10];
  int op, n = 0, age, telephone;
  string firstName, lastName;
  while (1) {
    // prints the menu
    cout << "1. Input information into an record." << endl;
    cout << "2. Display all information in all records." << endl;
    cout << "3. Exit the program" << endl;
    cout << "Enter option: ";
    cin >> op;
    switch (op) {
    case 1:                    //Input information into an record
      cout << "Enter first name: ";
      cin >> firstName;
      cout << "Enter last name: ";
      cin >> lastName;
      cout << "Enter age: ";
      cin >> age;
      cout << "Enter telephone number: ";
      cin >> telephone;
      rec[n] = Record(n + 1, firstName, lastName, age, telephone);
      n++;
      break;
    case 2:                    //Display all information in all records
      cout << "Record Number FirstName LastName Age Telephone-Number" << endl;
      cout << "-----------------------------------------------------" << endl;
      for (int i = 0; i < n; i++) {
        rec[i].print();
      }
      break;
    case 3:                    //Exit the program
      cout << "Exit the program." << endl;
      return 0;
    }
    cout << endl;
  }
}

> Record rec[10];
Isn't it just
std::array<Record, 10> a;
