Question

Option 1: Write a program that will: 1) read an array of records from the keyboard, 2) store this information to a binary file, 3) read from the binary file back to the array of records, 4) store this information to a textfile. Left justify the information for each field. Each record will consist of the following fields:

first name 15 characters last name 15 characters street address 30 characters city 20 characters state 5 characters zip long integer

You may assume a maximum of 20 records.
This assignment is very similar to the program found in Lab 12.3.

Sample Run:

Enter the following information Person

Explanation / Answer

#include <fstream>

#include <iostream>

#include <cctype> // for toupper function using namespace std;

const int NAMESIZE = 31;

struct Grades // declaring a structure

{

char name[NAMESIZE];

char city[15];

int zip;

};

int main()

{

char grade[NAMESIZE*2];

fstream tests("score.dat", ios::out | ios::binary);

// defines tests as an output binary file

Grades stu; // defines student as a record (struct)

char more; // used to determine if there is more input

do

{

cout << "Enter the following information" << endl; cout << " name: ";

cin.getline(stu.name,NAMESIZE);

cout << "City :";

cin.getline(stu.city,15);

cin.ignore(); // ignore rest of line

// write this record to the file

tests.write((char *) &stu, sizeof(stu));

cout << "Enter a y if you would like to input more data ";

cin >> more;

cin.ignore();

} while (toupper(more) == 'Y');

tests.close();

fstream tests("score.dat", ios::in | ios::binary);

fstream test2("score2.txt", ios::out | ios::binary);

test.read((char*) grade, sizeof(grade));

test2.write((char*)grade, sizeof(grade));

return 0;

}
