An input file is used as data source for a telephone directory program, the first line contains the full name of the phonebook owner, second line contains the number of contacts, each of the following line represent one contact and consists of the first name, followed by the last name and finally the phone number.

Create a structure called Person with the following data members:

ownerName

fName of type vector

lName of type vector

phone of type vector

Create the following functions:

void readFile(string filename,Person &p);

void saveFile(string filename,Person &p);

Int searchByfirstName(Person &p,string target), will return the index at which the contact last name target is found ( for simplicity search for the whole text == not find).

Int searchBylastName(Person& p,string target), same as above but will search in lName.

Int searchByPhone(Person &p,int phone), same as above but will search in phone.

Your main() should create an object of the Person structure and continuously ask the user for the required action from the following actions list:

1. Search by First Name.

2. Search by Last Name.

3. Delete by phone number.

4. Exit.

For the first 2 actions, your program should ask the user for the target and print the first name, last name and phone for the found contact, error message otherwise.

In Action 3, you should ask the user for a phone number and delete the contact who has it.

The last action is to save contact back into the file and exit the whole program.
