How do i open a binary file?

[seungyeon]

Write your question here.

fstream file("test.bin", ios::binary);

	if(file.is_open())
	{
		cout << "I am open." << endl;
	}
	else
	{
		cout << "re" << endl;
		return -1;
	}

Isn't it std::ifstream ? I haven't worked with files in ages...

[Thomas1965]

fstream file("test.bin", ios::binary);

That's one correct way.
The other is:

ifstream file("test.bin", ios::binary);

"text" files are binary files, by the way. The binary functions can be way faster for handing "text" files, depending on the size and what is being done. I know you wanted the syntax but this is important to know if you ever have to handle huge text files like generated xml gone wrong.
