Write the .txt "filename" into a file.

I am trying to put the filename that I am reading from to the file using this code:
The file is named ABC and this is what I want to write to the file: "file2".

I am trying to type in << myfile << but nothing is written to the file.
I want it to recognice what is written in the paratheses after the declaration of myfile. Is this possible in any way ?

Code:

---

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <sstream>
#include <string> 

using namespace std;

int main ()

{
        std::string Date;
        int Time = 0;
        char Comma;
       
        ofstream Test;
        Test.open ("file2.txt");
        ifstream myfile ("ABC.txt");

        getline(myfile, Date, ',');
        myfile >> Time;                        // 2111
        myfile >> Comma;

        if (Time == 2100)           
        {
        Test << myfile << Time <<"\n";   
        }

        return 0;
}

Well, you are for one thing trying to write an ifstream to the ostream, which I don't think is acceptable.

Huh?

Code:

---

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <sstream>
#include <string> 

using namespace std;

int main ()
{
        std::string Date;
        int Time = 0;
        char Comma;
       
        ofstream Test;
        Test.open ("file2.txt");
        ifstream myfile ("ABC.txt");

        getline(myfile, Date, ',');
        myfile >> Time;                        // 2111
        myfile >> Comma;

        if (Time == 2100)           
        {
                Test << myfile << Time <<"\n";   
        }

        return 0;
}

And as for fixing the indentation a little...

I see... Thanks for the corrections.
Could it be possible while reading the Date and Time from the file to also identify the filename from where it is red.
Could it be any approach to do it this way. I dont know if this makes any different ?

What do you mean by "identify the filename"? It's "ABC.txt" -- you have to know it beforehand in order to open your ifstream.

Edit: and I suppose if I take account the title of the thread, you can then do Test << "ABC.txt". If you want it to be more general, you can use a char[] as the name of the file to open, something like

Code:

---

char filename[] = "ABC.txt";

---

and use the variable name in both places.

Yes you are right.. I think I am mixing this up with another soulution for something else I want to do.. I do have the filename already in this case, thats correct...
Thanks...
