Time to apply what you know about file I/O, structs, and vectors in one complete program. You'll build a contact book that reads contacts from a file, displays them, searches for a specific one, and writes a summary back to a different file.
Write a program that does all of the following:
Contact struct with fields string name, string phone, and string email.vector<Contact> (use the values in the expected output below).contacts.txt, one per line in the format:Name | Phone | EmailContact: "Bob" and prints their phone number prefixed with Found: Total contacts: 4 at the end.#include <fstream>ofstream outFile("contacts.txt");for (auto& c : contacts) outFile << c.name << " | " << c.phone << " | " << c.email << "\n";outFile.close();
ifstream inFile("contacts.txt");string line;while (getline(inFile, line)) cout << "Contact: " << line << endl;inFile.close();
for (auto& c : contacts) { if (c.name == "Bob") { cout << "Found: " << c.phone << endl; break; }}
{"Alice", "555-1001", "alice@email.com"}{"Bob", "555-1002", "bob@email.com"}{"Carol", "555-1003", "carol@email.com"}{"Dave", "555-1004", "dave@email.com"}
