C Language Realizes Automatic Licensing

1. Initialize 54 cards
2. Randomly shuffle
3. Distribute to three people in turn
4. Display the cards in each person's hand

Note:
1. Mainly use random numbers, structures and arrays to realize
2. Constants are replaced by macros
3. Suits are represented by ASCII codes of 3, 4, 5, 6 and 1
