?? already submitted my answer but im confused

// Write a program that copies the data in the
// prelab input file to an output file "flux_capacitor"
// so that it is formatted the same in both files.
//
// Additionally add 30 to the year when you rewrite
// it to the output file to help Marty Mcfly get back to
// his proper time.

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

int main()
{
// declaring variables
string firstName;
string lastName;
int year;

// declare input file stream variable and open file
ifstream fin;
fin.open("prelab_input.txt");

// Test to see if file correctly opened. If statements will
// be learned in the future. For now, don't worry about
// understanding this.
if (!fin)
{
cout << "ERROR - File failed to open. make sure that "
<< "the input file and this file are in the"
<< "same directory" << endl;
return -1; // Return statement will terminate the program. We do not want
// to continue if we do not have a valid input file.
}

// declare output file stream varaible and open file
ofstream fout;
fout.open("flux_capacitor.txt");


// ADD HERE write your code here





// closing files
fin.close();
fout.close();

return 0;
}

We are just as confused, and we sadly aren't from the future so we don't know how this confusion will be resolved. :(

Without seeing any actual file formatting, I would start by doing something like this with your streams

// put space-delimited data from fin to corresponding variables
fin >> firstName;
fin >> lastName;
fin >> year;

// put data from variables into fout
fout << firstName;
fout << lastName;
fout << year + 30;

I think we'll need to see some file formatting if you want any good help,

and you should show what you've tried yourself so far.
