Lotto Simulation Help

[ckw77]

I think I got pretty much of the code, but I need help on the bottom. How do i define user and lottery.. Confused!! Also code is confusing so help also...

//Declarations

int matchCounter(int[], int[], int);
void displayNumbers(int[], int[]);
void displayhotball (int[], int[]);
