Question

write a program to score five card poker hands into one of the following categories: nothing, one pair, two pairs, three of a kind , straight(in order with no gaps), flush(all the same suit, for example, all spades),full house(one pair and three of a kind), four of a kind, straight flush(both a straight and a flush). use two arrays, one to hold the value of the card and one to hold the suit. Include a loop that allows the user to continue to score more hand until the user says the program should end.

Explanation / Answer

please rate - thanks
