This program simulates rolling dice to win or lose. It tracks the number of wins and losses over multiple rounds. In each round, two dice are randomly rolled and their values printed. If the dice match, the player wins; otherwise, they lose. After all rounds, a report is printed with the total games played and wins/losses. The user is prompted after each round to play again.
