If that's all you asked, I'm not surprised you got no answer.
BE SPECIFIC. We can't see your book from here. We don't know what "chars input" is supposed to be, and how your program, whatever it's doing, is not doing it.
Also, if this is homework, you need to post in the homework forum using the homework rules.

backgammon
BACKGAMMON(6) BSD Games Manual BACKGAMMON(6)
NAME
backgammon -- the game of backgammon
SYNOPSIS
backgammon [-] [-nrwb] [-pr] [-pw] [-pb] [-t term] [-s file]
DESCRIPTION
This program lets you play backgammon against the computer or against a "friend". All commands are only one letter, so you don't need to
type a carriage return, except at the end of a move. The program is mostly self-explanatory, so that a question mark (?) will usually get
some help. If you answer `y' when the program asks if you want the rules, you will get text explaining the rules of the game, some hints on
strategy, instructions on how to use the program, and a tutorial consisting of a practice game against the computer. A description of how to
use the program can be obtained by answering `y' when it asks if you want instructions.
The possible arguments for backgammon (most are unnecessary but some are very convenient) consist of:
-n don't ask for rules or instructions
-r player is red (implies n)
-w player is white (implies n)
-b two players, red and white (implies n)
-pr print the board before red's turn
-pw print the board before white's turn
-pb print the board before both player's turn
-t term
terminal is type term, uses /usr/share/misc/termcap
-s file
recover previously saved game from file
Any unrecognized arguments are ignored. An argument of a lone `-' gets a description of possible arguments.
If term has capabilities for direct cursor movement (see termcap(5)) backgammon ``fixes'' the board after each move, so the board does not
need to be reprinted, unless the screen suffers some horrendous malady. Also, any `p' option will be ignored. (The `t' option is not neces-
sary unless the terminal type does not match the entry in the /usr/share/misc/termcap data base.)
QUICK REFERENCE
When the program prompts by typing only your color, type a space or carriage return to roll, or
d to double
p to print the board
q to quit
s to save the game for later
When the program prompts with 'Move:', type
p to print the board
q to quit
s to save the game
or a move, which is a sequence of
s-f move from s to f
s/r move one man on s the roll r separated by commas or spaces and ending with a newline. Available abbreviations are
s-f1-f2
means s-f1,f1-f2
s/r1r2 means s/r1,s/r2
Use b for bar and h for home, or 0 or 25 as appropriate.
