Objective

The objective of this assignment is to give you practice with project and function design. It will also give you an opportunity to work with random numbers, arrays, passing arrays to functions, and using separate compilation.

War - A Modified Version of the Card Game

Your program will simulate the playing of a game of war with some minor modifications so that the game finishes within a resonable amount of time. The computer will handle the playing of cards by both of the players.

Our rules -

Each player will be dealt 26 cards from a shuffled standard deck of 52 playing cards, which the player will keep in a face-down stack.
A player plays a card by turning over the top card from his stack of cards.
For each hand of the game, each of the players will play a card.
The player with the highest ranking card wins both of the cards played and puts them in his winnings pile.
Aces are low. This means that an Ace plays as the number 1, the lowest card in the deck and does not beat the King.
If both cards played in a hand are of the same rank then that hand is tied and both cards are placed in the tied pile.
The winner of the next hand will take not only the cards played in that hand but also any cards that are in the tied pile and place them in his/her winnings pile.
Since each player gets 26 cards, there will be 26 hands played per game.
The player with the most cards in his winnings pile after the last hand is the winner of that game.
If both cards played in the last hand are the same, then those cards are placed in the tie pile, as usual, and remain there, never being awarded to either player.

While testing various seeds for the random number generator, I was surprised at how many times there were cards left in the tie pile at game's end. You will also investigate this by having your program play this game 100 times, using the numbers 1 through 100 as seeds for the random number generator. You must then report the number of games that ended with cards left in the tie pile.

Make sure that you print an explanation of the game to the user and have him press ENTER to begin the playing of the games. Otherwise the explanation will scroll off of the screen before the user gets to read it.

Specific Requirements

You must use two arrays of size 26 to hold the cards dealt to the player and to the computer. You must also use an array of counters when dealing so that you can guarantee that exactly four cards of each rank are dealt.

A Sample Run

Note - I'm only showing the beginning and the end of the sample run, since it is very long. What I've shown is enough to show you what is expected. It's WAR !!!

Submit as follows: submit cs201 Proj2 proj2.c war.c war.h The order in which the files are listed doesn't matter. However, you must make sure that all files necessary to compile your project are listed.
