I am trying to open a file with a program but it keeps failing. I typed the file into notepad and saved it as a .dat file. Does anyone have any ideas why this is happening?

Code:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <string>
using namespace std;

int main()
{
	string filename = "bank.dat";
	ifstream inFile;

	inFile.open(filename.c_str());

	if(inFile.fail())
	{
		cout<<"\nThe file named "<<filename<<" was not successfully opened"
			<<"\nPlease check that the file currently exists."
			<<endl;
		exit(1);
	}
	cout<<"\nThe file has been successfully opened for reading."
		<<endl;

	return 0;
}
