Question

Maximum allowed grace days: Zero Problem Statement: (Phone Book) Give functionality to phone.book.e by adding structures and functions Structures Create two stractures personal info and phone_book in a library hender named libpb.h. The structure phone.book holds an array of personal.info with up to 20 entries (struct personal.info [20]), as well as the number of people in the phone book (int num people). The maximum number of people in this phone book will be 30. The personal.info structure will hold 3 character arrays, the first name (char first [26)), the last name (char last (26]), and the phone number (char phone [15)) Functions 1: Write a funetion to ad a contact (personal.into) to the phone,book uning the prototype below void add.person(struct phone.book pb, struct personal.info persom) The phone.book.e prompts the user to enter the information as seen in the sample out put below. After the new contact information ?s entered, the program wil call the function nd.personand pa" this information to the function. In your function deinition you need to add this new contact to the phone.book. 2: Write a second function using the prototype below to search the phone book for a first name. Read the phone.book.e carefally. The phone.book.e pass this name to the function search t h.pb. In your function definition you need to search for all the contacts that matches the searched first name and print full information of each contact that has the same fist name with the format shown in the sample output void search.pb (atruct phose.book pb, char find.name t 1) Hint: To compare two strings, include the string.h lbrary in your libpb.c and use the function stremp(char *, char .), to linker flags are needed fr this library. stremo() returta 0 (or ?lar) if the eno ar, he sai You can use tatremp) to return true if they are the same. If there is no contact found, print 'No entries with that sane. Sample output for the program: 59

Explanation / Answer

// File Name: libpb.h
#ifndef LIBPH_H
#define LIBPH_H

// Defines a structure personal_info to store person information
struct personal_info

// Data member to store first name, last name and phone number
