What I have so far, it is supposed to be generating random numbers and then populating the correct element of the array. Keeps outputting 48 for all the printf() statements. Any ideas where I am messing up? I think it is in genRand() area or getTwoDieSum(). I am required to use the following shell, I am not really sure what everything is supposed to be doing which is why I am messing up. Also I am not really sure where the int lower and int upper are coming from in:

int genRand(int lower, int upper) {
     int range = (upper - lower) + 1;
     return rand() % range + lower;
    }

My question is more of where am I messing up and where is the int lower and int upper coming from and am I using the random seed generator correctly?
