C Programming - Lotto Simulation

I am making a program to simulate the lotto. The numbers can range between 1-45, but the numbers drawn must be unique. The program generates 6 random numbers in this range and adds them to an array. The user enters their numbers and the program checks if the 2 arrays are the same i.e whether they have won the lotto or not.

I don't know why, but my program doesn't generate the random numbers, nor does it check if they're equal.

Any help would be extremely helpful and I'd be even more grateful. :)
