You don t say what system you re using  but as you already have some answers that may or may not work for Windows  I ll answer for POSIX systems   In POSIX  keyboard input comes through something called a terminal interface  which by default buffers lines of input until Return Enter is hit  so as to deal properly with backspace   You can change that with the tcsetattr call    include  lt termios h gt   struct termios info  tcgetattr 0   amp info               get current terminal attirbutes  0 is the file descriptor for stdin    info c lflag  amp    ICANON          disable canonical mode    info c cc VMIN    1              wait until at least one keystroke available    info c cc VTIME    0             no timeout    tcsetattr 0  TCSANOW   amp info      set immediately      Now when you read from stdin  with getchar    or any other way   it will return characters immediately  without waiting for a Return Enter   In addition  backspace will no longer  work  -- instead of erasing the last character  you ll read an actual backspace character in the input   Also  you ll want to make sure to restore canonical mode before your program exits  or the non-canonical handling may cause odd effects with your shell or whoever invoked your program

Use the C Standard Library function getchar   instead as getch   is not a standard function  being provided by Borland TURBO C for MS-DOS Windows only  printf  quot Let the Battle Begin  n quot    printf  quot Press Any Key to Continue n quot      getchar           Here  getchar   expects you to press the return key so the printf statement should be press ENTER to continue  Even if you press another key  you still need to press ENTER  printf  quot Let the Battle Begin  n quot    printf  quot Press ENTER key to Continue n quot      getchar          If you are using Windows then you can use getch   printf  quot Let the Battle Begin  n quot    printf  quot Press Any Key to Continue n quot    getch         if you press any character it will continue       but this is not a standard c function    char ch  printf  quot Let the Battle Begin  n quot    printf  quot Press ENTER key to Continue n quot          here also if you press any other key will wait till pressing ENTER scanf  quot  c quot   amp ch     works as getchar   but here extra variable is required

Use getch     printf  Let the Battle Begin  n    printf  Press Any Key to Continue n    getch      Windows alternative should be  getch     If you re using Windows  this should be the full example    include  lt conio h gt   include  lt ctype h gt   int main  void         printf  Let the Battle Begin  n        printf  Press Any Key to Continue n         getch        P S  as  R  rd noted  if you re on POSIX system  you need to make sure that curses library is setup right
