I created a small program to read file.log and display it on the screen. My file.log looks like this
<br><br>
test1<br>
test2<br>
test3<br>
<br><br>
but my program display it like
test1test2test3

Here is my program looks like:

#include <fstream.h>
#include <iostream.h>

void read(char filename[]);

void main()
{
  read("file.log");
}

void read(char filename[])
{
 char tmp;
 ifstream fin;
 fin.open(filename, ios::in);

 while (fin.good())
 {
   fin >> tmp;
   if(!fin.good()) break; //check if reach end of file
   cout << tmp;
 }
 
 fin.close();  
}

If I put endl like cout << tmp << endl;
It will display:
t
e
s
t
1
t
e
s
t
2
t
e
s
t

You said what it does (test1test2test3) and what it does with the endl, but what do you WANT it to do?

Do you hav access to a string class. Try using this instead of the char variable. Usually things like reading from input streams are better wrapped in the a string class.

What you probably want to use is the getline member function (istream::getline). Because istream is the base class for ifstream you have access to that function for disk files too.
The function getline extracts the delimiter (default '\n'), but do not store it. If you don't want to extract/store the delimiter, use istream::get instead.

Hope this helps.
