More Card Game Problems

[CplusplusAcolyte]

Hello Everyone, I'm working on a WAR game and it's sort of a work in progress. The basic idea is that a single array holds values 1-52 with their positions randomized, representing a shuffled card deck, and each group of 13 values represents each suit. The first half of the array is the player's cards, and the second half the computer's (at least initially). As the game plays out, where the deck splits changes. Other variables are used to track where each player is drawing from in the deck, and the position of each player's draw moves outward from the center. When reaching the end of the array, regardless of which player it is, their cards are shuffled and position reset.
Mostly, the program seems to work, but sometimes it is falling outside of the array, resulting in incorrect card appearances and invalid card totals. Any help in pinpointing this problem would be appreciated.
