inStream practice problem not working?

Greeting,
Here is my code...
The question is that inStream has already been opened as a connection to an input file (data.dat) that contains the following data:
1 -2 3
4 -5 6
7 -8 9
and the the following declarations are in effect
int n1, n2, n3;
double r1, r2, r3;
char
c1, c2, c3,c4;

Code:

#include <iostream>	//cin,cout,<<,>>
#include <fstream>	//ifstream,ofstream	
#include <string>	//string, getline()
#include <cassert>	//assert()
using namespace std;

int n1, n2, n3;
double r1, r2, r3;
char c1, c2, c3, c4;

int main()
{
	cout << "This program computes values assigned to each of the variables \n"
                       << "in the input list and places its results in another file.\n\n";

	// ------------------input section--------------------------------

	cout << "Enter the name of the input file: ";
	  string inputFileName;
	getline(cin, inputFileName);	//get name of input file
	
	ifstream inStream;	//open an input stream to the input file
		inStream.open(inputFileName.data());	//establish a connection
	assert(inStream.is_open());	//check for success
	
	
		inStream >> c1 >> n1 >> r1 >> r2
		               >> n2 >> c2 >> c3 >> r3;	//read a value

		
	inStream.close();	//close the connection

	// ------------------------output section-------------------------

while(getchar() != '\n');

  cout << "Enter the name of the output file: ";
	string outputFileName;
	getline(cin, outputFileName);

	ofstream outStream(outputFileName.data());	//open an output stream to the output file
	// and establish a connection
	assert(outStream.is_open());	//check for success

	outStream  << c1 << n1 << r1 << r2
	                   << n2 << c2 << c3 << r3;	//write a value	
	
	outStream.close();	//close stream

	cout << "Processing complete.\n";

	return 0;
}

I should get the following answers according to the book:
c1 = '1' n1 = 23, r1 = 45.6 r2 = error--real numbers cant contain letters(ie 'X')

My is 1-234-567-8, I am
Can anyone explain why the book cam up with these answers to the practice problems?

can you please post your entire text file (.dat) so i can look at your logical approach...

b/c looking at your source code it doesn't seem to be wrong....maybe there's a logical problem along the way somewhere, b/c you are alternating your input from a file int, char, double and so on.....

plus it seems like your code is either missing something all it's written in an odd way....

what's with this line in your "output section"


while(getchar() != '\n');
