Getting incorrect reads from file read i

Getting incorrect reads from file read into array

When i run my program i get a long string of numbers and letters when i should be getting normal data.

ifstream fin;
	fin.open("data.txt");
	if(!fin)
	{
		cout << "Error opening file. Closing." << endl;
		exit(1);
	}

	for (int i = 0; i< COUNT; i++)
	{
		fin >> arrayOne[i]
		for (int j= 0; j< COUNT_TWO; j++)
		{
			fin >> arrayTwo[i][j]
		}

	}
	fin.close();

Here is the raw .txt data

2002
2.4 2.7 2.7 2.9 2.8 3.4 3.4 2.2 .9 1.1 1.7 1.9
2003
2.2 2.9 3.3 3.3 3.1 3.3 3.3 2.6 1.5 1.4 1.8 1.8
2004
2.2 2.7 3.1 3.8 3.6 4.0 3.6 2.9 1.7 1.8 2.4 2.1
2005
2.0 2.2 2.2 2.6 2.8 3.2 2.8 2.3 1.2 1.3 2.0 1.9
2006
2.0 2.2 2.2 2.6 2.9 3.1 2.4 1.7 1.0 1.9 2.3 1.9
2007
2.6 2.6 2.4 2.4 2.6 3.1 3.2 3.1 2.0 2.1 2.7 2.6
2008
2.3 2.5 2.2 2.3 2.5 2.5 1.7 1.7 1.0 1.3 1.5 1.9
2009
2.1 2.2 2.4 2.4 3.1 2.7 1.9 1.5 .9 1.9 2.7 2.3

Now i cannot figure out what is doing this. Any hints? My only guess right now is it has something to do with me needing an .ignore

The file reads in 2002 then 032FADC032FB3C and goes on and on and on.

EDIT: Also when i view the .txt in notepad, it shows what looks like a space, then a tab between each piece of data, and what seems to be a space and two tabs between both ".9"'s

Is there a way i can attatch the .txt to this post so everyone can see what im referring to? I cannot seem to find one
Nevermind, even erasing the tabs and leaving a single space doesnt fix it.

How do you know that you read 032FADC032FB3C ?
It looks like a pointer.

Also, what is declaration of your arrays?

I know because when i run the program it looks like that. 2002, then a new line, then the string of numbers, then reads 2003 another long string, then 2004 etc.

It seems instead of reading 2.4 then 2.7 it reads in "0032DADC" and "0032FB3C"

My declarations are

int arrayOne[COUNT];
double arrayTwo[COUNT][COUNT TWO];

also my constants
const int COUNT = 8
const int COUNT_TWO = 12

Can you modify your loop slightly:

		fin >> arrayOne[i]
		for (int j= 0; j< COUNT_TWO; j++)
		{
			fin >> arrayTwo[i][j];
                        cerr << arrayTwo[i][j] << " ";
		}
                cerr << endl;

and show output.

2.42.4 2.72.7 2.72.7 2.92.9 2.82.8 3.43.4 3.43.4 2.22.2 0.90.9 1.11.1 1.71.7 1.91.9
2003...

looks better, but its giving me numbers with two decimal points in them.

You are making double output (like << array[i][j] << array[i][j]), correct your code.

That got it. Forgot to erase the cout. However, my professor does not allow bits of code he has not gone over yet, and cerr is not part of any code we have discussed, so i cannot use it in my program. Is there another solution?

Use cout instead of cerr.
I prefer use cerr since it flushes immediately.
