The following program is in C:

Modify the following C program so that the card-dealing function deals a five-card poker hand. Then write the following additional functions: a) Determine whether the hand contains a pair. b) Determine whether the hand contains two pairs. c) Determine whether the hand contains three of a kind (e.g., three jacks). d) Determine whether the hand contains four of a kind (e.g., four aces). e) Determine whether the hand contains a flush (i.e., all five cards of the same suit). f) Determine whether the hand contains a straight (i.e., five cards of consecutive face values).
