quick question on fstream

[toast28]

Hey, I need to open a file in my newest program. I need it to simulate the log on of an operating system. It needs to read in a database of usernames and then output any attempts to log in, either allowed or denied.

My problem is that when I restart my program, it rewrites the entire output file. I need it to read the output, and stop right before the eof().

I tried using
while(!outfile.eof())
outfile >> junk;

but that brings me all the way to the end of file and won't write any more. Any ideas?

Especially look at how I opened the file.
"ios::app" means, "append".

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

std::ofstream outfile("namelog.txt", std::ios::app);

int main()
{
  std::string sName("Alex Bosman");
  
  //Otherwise the names will be concat. on the same line.
  outfile << std::endl;
  outfile<<sName;
 
  return 0;
}
