Why isn't the file opening?

[jp01cf01]

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

int main ()
{
  string line;
  fstream technologic ("daftpunk.bin", ios::out | ios::in | ios::binary);
  if (technologic.is_open())
  {
	cout << "It is open\n";
    technologic.close();
  }

  else cout << "Unable to open file\n"; 

  return 0;
}

Why isn't it opening the file?

try putting " technologic. open(("daftpunk.bin", ios::out | ios::in | ios::binary); " after ifstream technologic
I am currently working on ifstream in class and that is how I have my program set up and it opens. Hope it helps. I am just a beginner programmer,

It didnt work :/

I think you can't open with ios::in and ios::out try using ifstream.

[dolpator]

did you change fstream technologic to ifstream or ofsteam. I think you have to initialize it as input or output. I enjoy reading and trying to figure things out so I learn as well. Hoping it will make me better.

Did you create the file daftpunk.bin?

[jp01cf01]

i tried ifstream and ostream, and it didnt work, and I thought that if the file wasnt already made, it would make it for you?

[Peter87]

I don't think it will if you pass ios::in

It looks like your fstream parameter is incorrect. You're trying to do input and output at the same time.

You can learn about fstream and file input/output in the Documentation Section: http://www.cplusplus.com/doc/tutorial/files/

I can see no problem with the original code; fstream can be used with both ios_base::in and iso_base::out. This is, in fact, its default open mode:

Where are you trying to create the file? You could try specifying a full path to your file and see if that makes a difference.
