  getstr(name);
  if (*name == 'a')
    algorithm();
  else
    printw("%s","algorithm error");
  refresh();
  sleep(2);
  endwin();
  exit(EXIT_SUCCESS);
}

error: Segmentation fault(core dumped)
why???

I think that maybe it is abnormal to run the function "algorithm(system)", but I don't find out ?where.

(gdb)core a.core
Core was generates by 'a'.
Program terminated with signal 11, Segmentation fault.
