Question

I’ve been having some trouble with a guessing game that populates an array with random integers, and then has the user try to guess a number in the array. I believe I have most of it correct, but the program will not go beyond the “Initializing lucky numbers…” print command for me to check whether my functions are working or not. I believe the problem either lies with how I’m passing the array to the functions, or how I’m calling the functions (perhaps in their prototypes?) Any help would be greatly appreciated.
This is my first post, so I apologize if I was unable to correctly include the code. Thank you!

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <time.h>

/*
This program is a lucky number guessing game. A series of unique, random numbers 
will be generated and stored in an array. Users will have up to three chances to
guess a number stored in the array.*/

uniqueFlag needs to be reset whenever you pick a random number, not just at the start of the outer loop in fillArray.
