Read char from text file always result in extra one line

[pauljoseph]

Hi,
I would appreciate if someone can advise me on this issue. I am trying to write a program that read a text file. The input of the text file looks like this:

15	50	Y
13	70	Y
13	100	N
18	250	Y
17	110	N
16	200	N
16	80	Y

Now the last column should be read as a character. However, when I read in as a char, it always count that I am reading 8 lines (the actual text file is only 7 lines). When I use a string to read in the last column, it results fine in reading only 7 lines.

The code that I am using is this:

#include<iostream>
#include<fstream>
#include<string>

using namespace std;

int main()
{
	const int MAX=1000;
	int age[MAX];
	double mpm[MAX];
	char resp[MAX];     // If I use char, it reads 8 lines
	//string resp[MAX]; // If I use this, it reads 7 lines
	int size;
	double mpmAverage;
	ifstream myFile;

	myFile.open("survey1.txt");
	if(!myFile)
	{
		cout<<"Unable to open File!\n";
	}
	else
	{
		int i=0;
		double mpmSum=0;
		while(!myFile.eof())
		{
			myFile>>age[i]>>mpm[i]>>resp[i]; //This is the part for reading the data
			mpmSum+=mpm[i];
			i++;
		}
		size=i;
		mpmAverage=mpmSum/size;
		cout<<"\t\t\t Survey Report\n";
		cout<<"A total of "<<size<<" teenagers were surveyed.\n";
		cout<<"Average monthly pocket money = $"<<mpmAverage<<endl;

	}
	myFile.close();
	return 0;
}

It seems it is related with the EOF character. I would appreciate if someone can explain me in clear sentences what is happening. And how should I do it if I want to use char as my data type?

Thanks in advance.
