Task #

Write a roulette simulator using processes communicating through pipes. The program takes two parameters: number of players N (N ≥ 1) and player starting money M (M ≥ 100).

Players bet on a single number [0, 36] with a 35:1 payout. The winning number is chosen randomly from [0, 36].

Stages #

1. The dealer (main process) creates N player processes. Each player prints: [process id]: I have [amount] and I'm going to play roulette.

2. Players communicate with the dealer via pipes. Each player sends a bet amount (within their balance) and a chosen number.

   • The dealer prints: Dealer: [process id] placed [amount] on [number] after receiving a bet.
   • The dealer draws a random number and announces: Dealer: [number] is the lucky number.
   • After one round, all players and the dealer exit.

3. The game continues as long as at least one player has money.

   • If a player runs out of money, they print: [process id]: I'm broke and exit.
   • If a player wins, they print: [process id]: I won [amount].
   • Once all players exit, the dealer prints: Dealer: Casino always wins and exits.

4. Each round, a player has a 10% chance to leave with their remaining money. They print: [process id]: I saved [amount left] and exit.
