Accept user input to open file

[jkcalz]

I'm trying to accept user input to open up a .dat file that's in my source files but I don't know why the file keeps failing to open

#include <iostream>
#include <string>
#include <fstream>
#include "arrayFunctions.h"

using namespace std;

int main()
{
   string fileName;
   int size = 0;
   ifstream inputFile;
   do
   {
	cout << "Please enter file name: ";
	getline(cin,fileName);

	inputFile.open(fileName.c_str());
	if (!inputFile)
	{
	   cout << "The file \"" << fileName << "\" failed to open.\n"
		<< "Check to see if the file exists and please try again" 
                << endl << endl;
	}
	while (inputFile.good())
	{
		string stop = " ";
		string num;
		getline(inputFile, stop);
		size++;
	}
   } while (!inputFile);

   cout << size << endl << endl;
   inputFile.close();

   system("pause");
}

Try this to see a better error msg.

#include <stdio.h>
if (!inputFile)
{
   perror("File error");
}
