Help

I've written my code for my homework, but when I execute it, rather than displaying the content of the file, it gets erased.

I can't figure out what I'm doing wrong.

Here's what I've written.

Code:

#include <iostream>
#include <fstream>
#include <cstdlib>

using namespace std;

int main ()
{
    char next, advice;
    
    ifstream fin;
    ofstream fout;
    
    fin.open ("F:\\CS 2\\advice.txt");
    fout.open ("F:\\CS 2\\advice.txt");
    
    if (fin.fail())
    {
       cout << "File failed to open.\n";
       system ("pause");
       exit (1);
    }
    
    if (fout.fail())
    {
       cout << "File failed to open.\n";
       system ("pause");
       exit (1);  
    }      
    
    
    while (fin >> next)
    {
    fin.get(next);
    cout << next;
    }
    
    cout << "\n\n" << "Input your own advice.\n";
    cin >> advice;
    
    while (! cin >> '\n')
    {
    cin.get(advice);
    fout << advice;
    }
    
    fin.close ( );
    fout.close ( );
    system ("pause>nul");
}

you need to open the fout stream in append mode

Code:

 ofstream fout("F:\\CS 2\\advice.txt", ios:: app);

You're using the same file for input and output.
