  5. // * This program simulates a simple lottery game. It generates five random numbers        *
  6. // * (0–9) and asks the user to enter five guesses. The program compares the user’s        *
  7. // * numbers to the lottery numbers and counts how many match. If all match, the user      *
  8. // * wins the grand prize.                                                                 *
