read to end of line problem

I'm kicking myself because this isn't working. Basically, I need to read a bunch of numbers from an input file to an array and sort them. My problem is, I'm supposed to stop at the end of the line, sort that array, then read another line, sort that, and so on. I'm having trouble getting the loop to stop inputing at the end of the line. Using chars, I can get it to recognize the end of line character ('\n'), but using integers this doesn't work. Any ideas? My input text is listed below to give you an idea of what I'm talking about:


data.txt:

9132574
8742323523498723648
23423
21342354324523467

Maybe:

Post your code too.

Or maybe something like:

Code:

---

#include <iostream>

int main(void)
{
  int ch;
 
  while ((ch = std::cin.get()) != EOF)
  {
    if (ch == '\n')
    {
      std::cout <<"End of line reached" <<std::endl;
    }
  }
 
  return(0);
}

What's wrong with reading it as char's. Just subtract the ascii value for '0' from the char that was read.

eg. if you read '9', then '9' - '0' will give you the integer value 9.

Dunno why I can't read as char's, my prof is a jerk about it for some reason. I have this whole thing working using chars, output looks perfect. He's making me re-do it and I can't get it working. It's really annoying. I'll try the above mentioned code.
