I am writing a program for my college class It has to record a password, but it cant display it on the screen. It is a unix based enviroment. Does this look correct to you guys?

Code:

 main()
{
  int  i;
  char buffer[80];            
  initscr();                

  printw("Please enter a password => ");    
  refresh();                
  noecho();                
                    
  while((buffer[i] = getch()) != '\n') i++;

  printw("\nPassword is %s - press return to continue.",buffer);
  refresh();
  getch();

  endwin();                 }
