I'm using .NET.

Ok, here's the problem. If I don't create a file named "house.txt" before executing this program (I thought that open creates a file automatically if it doesn't already exists), it won't create the file automatically. What I'm trying to do is have the program create a file automatically if one already doesn't exist and if one already exists, simply truncate what's inside. Any ideas?
#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main()
{
string file_name = "house.txt";
fstream binary_file;

binary_file.open(file_name.c_str(), ios::out | ios::trunc | ios::in | ios::binary);

if(binary_file.good())
{
cout << "The file was opened..." << endl;
}
else
{
clog << "The file was not opened..." << endl;

exit(0);
}

for(int i = 0; i < 10; i++)
{
binary_file.write((char * )( & i), sizeof(int));
}

binary_file.seekg(ios::beg);

int test = 0;

for(i = 0; i < 10; i++)
{
binary_file.read((char * )( & test), sizeof(int));

cout << test << " ";
}

binary_file.close();

cout << endl << endl;

return 0;
}
