# rounds argument is the number of rounds to play war

About the program(s)

1. war_pipes.c
   • Forks two child processes to play rounds of war
   • Parent process is the game keeper and makes all requests
   • Message passing is implemented with uni-directional pipes
2. war_sockets.c
   • Creates two child threads to play rounds of war
   • Parent process is the game keeper and makes all requests
   • Message passing is implemented with local host socket
3. War game logic
   • Each round, the parent request each child to draw a card
   • In the case of a tie, the parents request each childs suit
     • If the suits are also tied, the round has no winner
   • After each round, the winning child gets +1 point
     • Card scoring values are the same for a typical card game
   • Once all rounds are completed, the results are tallied
