Problem 2 (Save and Get Info) : Write a program that asks for the user's name, phone number, and address. The program then saves all information in a data file (each information in one line) named list.txt. Finally, the program reads the information from the file and displays it on the screen  in the following format:

Name: User's Name  
Phone Number: User's Phone Number  
Address: User's Street Address
User's City, State, and Zip Code

Solution

Code

#include <fstream>
#include <iostream>
using namespace std;

int main ()
{
  
char data[100];

ofstream outfile;
outfile.open("list.txt");

cout << "Writing to the file" << endl;
cout << "Enter User name: ";
cin.getline(data, 100);

  
outfile << data << endl;

cout << "Enter your phone number: ";
cin >> data;
cin.ignore();

outfile << data << endl;
cout << "Enter your Address: ";
cin >> data;
cin.ignore();

outfile << data << endl;
cout << "Enter your City: ";
cin >> data;
cin.ignore();

outfile << data << endl;

cout << "Enter your State: ";
cin >> data;
cin.ignore();

outfile << data << endl;

cout << "Enter your zip code: ";
cin >> data;
cin.ignore();

outfile << data << endl;

outfile.close();

ifstream infile;
infile.open("list.txt");

cout << "Reading from the file" << endl;
infile >> data;

cout <<"Name: "<< data << endl;

infile >> data;
cout << "Phone Number: "<<data << endl;

infile >> data;
cout << "Address: "<<data << endl;

infile >> data;
cout <<"City: "<< data << endl;

infile >> data;
cout << "State: "<<data << endl;

infile >> data;
cout <<"Zip Code: "<< data << endl;
infile.close();

return 0;
}
