Question

I’m trying to read from files created outside of the program, but am having some trouble. The program has the user create a file. Then it reads words from two .txt files created outside of the program, and then writes the words to the created file.

#include "std_lib_facilities.h"

int main()
{
    string word;

    cout << "Create file.\n";
    char name[20];
    cin >> name;
    ofstream ost(name, ios::out);

    cout << "Open first file.\n";
    char filename[20];
    cin >> filename;      
    ifstream ist(filename);
    while(ist >> word) ost << word << " ";
    ist.close();

    cout << "Open second file.\n";
    cin >> filename;
    ifstream isttwo(filename);
    while(isttwo >> word) ost << word << " ";
    isttwo.close();

    ost.close();

    keep_window_open();
}

However, when I open the created file in notepad, it comes out blank. Is this because reading into a string is impossible because the files being read were created separately? I’m not really sure. Any help is appreciated.

Answer 1

The code is correct. Just make sure when you write the name of the first file and the second one you write their extensions as well.
For example :

first.txt
second.txt
