problems when reading from a text file

[stav]

im trying to learn about the fstream in c++
and so i tried to make a program that read from and printed it out on the console
but something very wired happened..

so i have these two files:
testy.txt
&
db.txt


the testy.txt is one that i made myself and all it contains is:

this is a test
this is another
this is a third

the db.txt is one i got of the internet so that i had something to run my program on and all it contains is database information like this:

('RWIN', 'b64a850dedf106fdf6c11f09e6369d52', '[e-mail]', '', '87.195.246.56'),
('brentje', '6ebe76c9fb411be97b3b0d48b791a7c9', '[e-mail]', '', '212.187.55.190'),
('Joe', '9e272443ac7e33396caeb85e66905063', '[e-mail]', '', '84.85.66.148'),

('PHOENiX.', '1a850d3f283c01002dd2d075d2518ff7', '[e-mail]', '', '82.72.94.243'),
...

and now heres my program:

#include <iostream>
#include <fstream>


using namespace std;

int main()
{
	

	ifstream iFile("testy.txt");

	if (!iFile.is_open())
		return -1;

	
	const int buffer = 10000;
	char line[buffer];
	

	while(iFile.getline(line, sizeof(line) / sizeof(char)))
		cout << line << endl;


	char temp;
	cin >> temp;

	
	
	return 0;
}

when i run it with the testy.txt file i get:
this is a test
this is another
this is a third
,as expected.

but when i run it with the db.txt something really wired happens and i just get a blank screen?

and on my console the scrollbar has rolled all the way down, as if its just put a bunch of blankspace instead of the file content?

why is this happening?
