  fflush(stdout);

  Also, in Gnu C/C++ stdout's buffer is automatically flushed when anything is
read from stdin (usually = from the keyboard), so these will work:-

  printf("name of experiment?"); gets(exptname);

  double ask(char*s) {double x; char buf[512];
  X: printf(s); gets(buf); if(sscanf(buf,"%lf",&x)<1) goto X; return x;}
  ...
  weight=ask("weight of sample?");
