Question

create code for an address book console program in C++ that:

1. Uses a basic array in the main program to hold multiple Record class objects.
2. A Record class is to be constructed with the following member variables:
   1. Record number,
   2. first name,
   3. last name,
   4. age, and
   5. telephone number.
3. The Record class must have a custom constructor that initializes the member variables.
4. The Record class declaration is to be separated from the Record class implementation and these are to be placed in .h and .cpp files respectively.
5. The program should have a perpetual menu that allows a choice of:
   1. Input information into an record,
   2. Display all information in all records, and
   3. Exit the program.
6. The program should hold 10 records at the minimum.

#include <iostream>
#include <string>
using namespace std;
class Record{ //.H FILE RECORD
private: //PRIVATE MEMBER
int recordNumber;
string firstName;
string lastName;
int age;
int telePhone;
public:
Record(); //DEFAULT CONSTRUCTOR
Record(int,string,string,int,int); // PARAMETERIZE
void display(); // DISPLAY FUN
void setData(int,string,string,int,int); // EXTRA FUN MUTATOR
};
Record::Record(){
recordNumber=0;
age=0;
telePhone=0;
// STRING IS NULL BY DEFAULT
}
Record::Record(int rec, string first, string last, int ag, int phone){
// PARAMETERIZE CONSTRUCTOR
recordNumber=rec;

}
