C program of a game like the famous Card game-"Heartz"

/* This game is played between two players. Each player will be given 13 cards with alphabet written on them. Each card will have a distinct value between 0 and 1000.These numbers are not visible to the players. Each player is required to throw a card on his turn. If the card thrown by a player has higher value than the card thrown by the former player then that card is won by the player of the highest card value. Then it is his turn to throw a card next. Player with all the card is the winner. */
