Hi,

I just made my first c++ program, and I would like to know if there are
things I can do better. Also, the exe is about 500 kb, can I make it
smaller?

Thanks!
Pieter

#include <string>
#include <fstream>
using namespace std;

int main()
{
  string buffer;
  string includebuffer;
  string bestand;
  string configin;
  string configout;

  ifstream config("config.txt");
  getline(config, configin);
  getline(config, configout);
  config.close();

  ifstream infile(configin.c_str());
  ofstream outfile(configout.c_str());

  while (getline(infile, buffer))
  {
    if (buffer == "")
    {
      outfile << " " << endl;
    }
    else
    {
      if (buffer.substr(1,7) == "include")
      {
        bestand = buffer.substr(9, (buffer.find_first_of("}") - 9));
        bestand += ".tex";
        ifstream includefile(bestand.c_str());
        while (getline(includefile, includebuffer))
        {
          outfile << includebuffer << endl;
        }
        includefile.close();
      }
      else
      {
        outfile << buffer << endl;
      }
    }
  }

  infile.close();
  outfile.close();
  return 0;
}
