Poker hand V43542
Write a function that given 3 Poker cards returns a description (a string) of the hand they represent. The description must be one of the following four possibilities: "Trio of Aces!", "Trio", "Pair", or "All cards different".
The cards are one of the following 13 characters: A, 2, 3, ..., 9, 0, J, Q, K. There are two characters worth explaining: the card A is the Ace and represents 1, as in normal decks, and the digit 0 represents 10, to simplify reading.
The function header is, exactly:
/**
* @pre c1, c2, c3 in {A, 2, 3, ..., 8, 9, 0, J, Q, K}
* @post Returns "Trio of Aces!", "Trio", "Pair", or
* "All cards different" according to c1, c2, and c3.
*/
string poker_hand(char c1, char c2, char c3);
Observation
You only need to submit the requested function; the main program will be ignored.
Sample session
poker_hand('A', 'A', 'A') => "Trio of Aces!" poker_hand('4', '4', '4') => "Trio" poker_hand('A', '1', 'A') => "Pair" poker_hand('Q', 'Q', 'A') => "Pair" poker_hand('A', '9', '9') => "Pair" poker_hand('1', '5', '8') => "All cards different"
