Not sure how to create this function ---> void initRaffle(int raffles[MAXRAFFLE]);

The paramters are:

Pre-conditions: raffles is the collection of all possible raffle tickets

Post-condition: Each raffle ticket should have a default owner number that indicates it has not been sold yet What to do in this function: Each index number represents a different ticket number for the Raffle.
