The [[wp:Pig (dice)|game of Pig]] is a multiplayer game played with a single six-sided die. The object of the game is to reach '''100''' points or more. Play is taken in turns. On each person's turn that person has the option of either:
:# '''Rolling the dice''': where a roll of two to six is added to their score for that turn and the player's turn continues as the player is given the same choice again; or a roll of '''1''' loses the player's total points ''for that turn'' and their turn finishes with play passing to the next player. :# '''Holding''': the player's score for that round is added to their total and becomes safe from the effects of throwing a '''1''' (one). The player's turn finishes with play passing to the next player.
;Task: Create a program to score for, and simulate dice throws for, a two-person game.

Ada
Uses Ada 2012.
The Package Pig
We first define a package Pig, which we also use in the player task [[Pig the dice game/Player]].
Essentially, this package specifies two classes: Player provides the record keeping of the player's score saved so far, the points accumulated in the current round that may be added to the score, and the most recent roll. Actor is an abstract class to model the decision of rolling the dice once more or to save the current points into the score.
Also, there is a procedure Play to play the game, following whatever the actors do.
package Pig is
type Dice_Score is range 1 .. 6;
type Player is tagged private;
function Recent(P: Player) return Natural;
function All_Recent(P: Player) return Natural;
function Score(P: Player) return Natural;
type Actor is abstract tagged null record;
function Roll_More(A: Actor; Self, Opponent: Player'Class)
return Boolean is abstract;
procedure Play(First, Second: Actor'Class; First_Wins: out Boolean);
private
type Player is tagged record
Score: Natural := 0;
All_Recent: Natural := 0;
Recent_Roll: Dice_Score := 1;
end record;
end Pig;
The implementation of Pig is as follows:
with Ada.Numerics.Discrete_Random;
package body Pig is
function Score(P: Player) return Natural is (P.Score);
function All_Recent(P: Player) return Natural is (P.All_Recent);
function Recent(P: Player) return Natural is (Natural(P.Recent_Roll));
function Has_Won(P: Player) return Boolean is (P.Score >= 100);
package RND is new Ada.Numerics.Discrete_Random(Dice_Score);
Gen: RND.Generator;
procedure Roll(P: in out Player) is
begin
P.Recent_Roll := RND.Random(Gen);
if P.Recent = 1 then
P.All_Recent := 0;
else
P.All_Recent := P.All_Recent + P.Recent;
end if;
end Roll;
procedure Add_To_Score(P: in out Player) is
begin
P.Score := P.Score + P.All_Recent;
P.All_Recent := 0;
end Add_To_Score;
procedure Play(First, Second: Actor'Class;
First_Wins: out Boolean) is
P1, P2: Player;
begin
loop
Roll(P1);
while First.Roll_More(P1, P2) and then P1.Recent > 1 loop
Roll(P1);
end loop;
Add_To_Score(P1);
exit when P1.Score >= 100;
Roll(P2);
while Second.Roll_More(P2, P1) and then P2.Recent > 1 loop
Roll(P2);
end loop;
Add_To_Score(P2);
exit when P2.Score >= 100;
end loop;
First_Wins := P1.Score >= 100;
end Play;
begin
RND.Reset(Gen);
end Pig;
Solving the Task
Now, to actually '''play''' the game, we need a procedure Play_Pig. Mainly, we derive a class Hand from the class Actor to implement manually playing the game.
with Pig, Ada.Text_IO;
procedure Play_Pig is
use Pig;
type Hand is new Actor with record
Name: String(1 .. 5);
end record;
function Roll_More(A: Hand; Self, Opponent: Player'Class) return Boolean;
function Roll_More(A: Hand; Self, Opponent: Player'Class) return Boolean is
Ch: Character := ' ';
use Ada.Text_IO;
begin
Put(A.Name & " you:" & Natural'Image(Self.Score) &
" (opponent:" & Natural'Image(Opponent.Score) &
") this round:" & Natural'Image(Self.All_Recent) &
" this roll:" & Natural'Image(Self.Recent) &
"; add to score(+)?");
Get(Ch);
return Ch /= '+';
end Roll_More;
A1: Hand := (Name => "Alice");
A2: Hand := (Name => "Bob ");
Alice: Boolean;
begin
Play(A1, A2, Alice);
Ada.Text_IO.Put_Line("Winner = " & (if Alice then "Alice!" else "Bob!"));
end Play_Pig;

The game is built around the PigPlayer type, which contains the player information, including a reference to the strategy function, strat, that is to be used to determined whether a player is going to continue to roll. In this incarnation of the game, there is only one strategy function available, pig_manual, which gets this decision from user input.
