Write a program in c++ that maintains a telephone directory. The Telephone directory keeps records of peoples names and the corresponding phone numbers.

The program should read a transaction file and report the result into an output file. The transaction file can include commands such as Add, Delete, Display, and Update, and Search. Each command is written in one line with a few other information.

The Display Command should simply display everyone in the directory on the screen

The Add command comes with 3 other information that includes First Name, Last Name, and Phone Number. You should only add this command if the phone number is unique and it is not assigned to any other person. Otherwise an error statement should be generated to indicate that Duplicate phone number is not allowed. If the addition of the record is successful, you need to report that in the output file as follows:

First Name, Last Name, Phone Number has been successfully added to the directory

If the addition fails, you should report that

**** ERROR IN ADD **** Phone Number already exist in the directory

The Delete command comes with the Phone Number indicating that this record should be deleted from the directory. You should only delete the record if you can find the phone number. If you could remove the record from the directory, you should report:

First Name, Last Name, Phone Number has been successfully deleted from the directory

If the delete fails, you should report that

**** ERROR IN DELETE **** Phone Number does exist in the directory

The Update command come with two values, Phone Number and New Phone Number. You program should first search for Phone Number and find out if such a phone number exist in the directory. If it does not find it, it should report:

**** ERROR IN UPDATE **** The Phone Number does not exist in the directory

However, if it finds the phone number, there are two cases. If the New Phone Number already exists in the directory, it should report

**** ERROR IN UPDATE **** The New Phone Number New Phone Number already exist in the directory.

If the New Phone Number does not exist in the directory, your program should replace the Old Phone Number with the New Phone Number and report

The Phone Number Old Phone Number is successfully updated to New Phone Number

There are two types of Search commands. One is done based on the last name and another is done based on the phone number. If it is done based on the last name, the search command can be as follows:

Search BasedOnLastName LastName

In this case the search is done based on the last name. Your program should search for all records with that last name and report them on the screen. If the search fails your report should have the following format

**** ERROR IN SEARCH **** No Record with the last name Last Name could be found

If the search is done based on the phone number, the command should be

Search BasedOnPhoneNumber PhoneNumber

In this case the search is done based on the Phone Number. Your program should search for the specific record with that phone number and if it finds it, it should report it

FirstName LastName PhoneNumber is found

on the screen; otherwise, it should display

**** ERROR IN SEARCH ****: No Record with the phone number Phone Number Exist

You are required to create a vector with class called PhoneRecords.

class PhoneRecords

{

Public:

string Fname;

string Lname;

string PhoneNumber;

};

Every time a record is added it should be added to vector. You can simply use the push_back operation to add it to the end of the vector. Use the following Transaction file to do run your work.
