Must convert libpb.c and libpb.h to compatible c++ code to work with main.cpp

Replace all of the C code in libpb.c and libpb.h (provided in the supplementary folder) with C+ code. Rename libpb.c to libpb.cpp and libpb.h to libpb.hpp. Convert the personalinfo structure into a class with three private data member strings for the first name, last name, and phone num ber. To access private members of a class, there are typically public get and set functions. Get/set member function prototypes for the data members of the class personalinfo are shown below (to be added into your libpb.hpp file). There is a get and a set for each private data member. A set function will set the private member equal to the functions input. A get function will return the private member's value. This is typically good practice for things that should not be accessed directly (think of them as hidden from the end user).

Explanation / Answer

/*libpb.hpp*/

class personal_info{

   private:
      string first;
      string last;
      string phone;

   public:
      void setfirst(string a);
      void setlast(string a);
      void setPhone(string a);
      string getfirst();
      string getlast();
      string getphone();
};

class phone_book {
    private:
        vector<persona_info> list;
    public:
        void add_person(personal_info p);
        void search_pb(string a);
        int get_num_people();
};   

/*libpb.cpp */

#include<iostream>
#include<string>
#include<iomanip>

using namespace std;

#include "lipb.hpp"

void personal_info::setfirst(string a){
          first = a;
}
void personal_info::setlast(string a){
          last = a;
      }
void personal_info::setPhone(string a){
          phone = a;
}
string personal_info::getfirst(){
          return first;
}
string personal_info::getlast(){
          return last;
}
string personal_info::getphone(){
          return phone;
}

void phone_book::add_person(personal_info p){
     list.push_back(p);
}
void phone_book::search_pb(string a){
     int found = 0;
     for (int i = 0; i<list.size(); i++){
         if (list[i].getfirst() == a){
              cout << list[i].getfirst() << " " << list[i].getlast() << list[i].getphone() << endll;
              found = 1;
         }
     }
     if (found == 0)
        cout << "Not found ";  
}
int phone_book::get_num_people(){
     return list.size();
}
