It's a known bug, but unlike most of them this one actually has a known
fix. See the Dinkumware site at http://www.dinkumware.com/support.html .

Hi all,

I want to wait sometimes till a user presses the Return-Key, so I wrote
a method to wait for Return. This works fine, but the very first time I
call this method I have to press enter twice to get one result. I use
std::cin included from <iostream> in vc 5.0.

source:

  char *c=new char[255];
  std::cout <<"\nplease hit enter.";// this appears only once - but I
have to hit 'ENTER' twice - but only the very first time?!?
  std::cout.flush();

  std::cin.getline(c,255);
  delete [] c;

tia
    Andreas
