Jumble solving program crashes on run - c

Question

I'm working on a program for my Intro to C class that requires me to write a program that solves jumble puzzles (you know, those anagram puzzles you see in the newspaper), based on a dictionary text file that my professor gave us. It alphabetizes words from the dictionary, takes in jumbles from a text file (called "jumble.txt"), alphabetizes those, then runs a string compare to find a match. I've got all the code written, but it immediately crashes when I try to run it, and I can't figure out why. I thought maybe the Stackoverflow users might be able to help me out here.
Here's the code I have:
#include <stdio.h>
#include <strings.h>
#define MAX_WORD_LEN 6
#define MAX_NUM_WORDS 30000
typedef struct {
char word[MAX_WORD_LEN+1];
char sort[MAX_WORD_LEN+1];
} jumble_type;
void bubblesort(char letters[], int length);
int main () {
int words, jumbles;
int j, q;
jumble_type list[MAX_NUM_WORDS];
jumble_type list2[MAX_NUM_WORDS];
// Creating file pointers
FILE *ifp;
FILE *ifp2;
//Opens Jumble and dictionary files and reads the info from them
ifp = fopen("jumbledct.txt", "r");
ifp2 = fopen("jumble.txt", "r");
//Assigns the value of "words" to the first line of jumbledct.txt
fscanf(ifp, "%d", words);
//Assigns the value of "jumbles" to the first line of jumble.txt
fscanf(ifp2, "%d", jumbles);
// Reads the words from the dictionary into the "word" section of our
// list structure.
int i;
for (i = 0; i < words; i++){
fscanf(ifp, "%s", &list[i].word);
strcpy(list[i].sort, list[i].word);
bubblesort(list[i].sort, strlen(list[i].sort));
printf("%s\n", list[i].sort);
}
//Reads from Jumble.txt
for (i = 0; i < jumbles; i++){
fscanf (ifp2, "%s", &list2[i].word);
strcpy(list2[i].sort, list2[i].word);
bubblesort(list2[i].sort, strlen(list2[i].sort));
//printf("%s\n", list2[i].sort);
}
for(j=0;j<jumbles; j++){
printf("JUMBLE PUZZLE # %d: %s\n", j+1, list2[j].word);
int x=0;
for (q = 0; q < words; q++){
if(strcmp(list2[j].sort, list[q].sort)==0){
printf("%s\n", list[q].word);
x++;
}
}
if (x == 0){
printf("Sorry, this puzzle has no solutions. \n\n");
}
printf("\n");
}
return 0;
}
void bubblesort(char letters[], int length) {
char temp;
int x, y;
for(x = 0; x < length; x++){
for (y = x; y < length; y++){
if (letters[x] > letters[y]){
temp = letters[y];
letters[y] = letters[x];
letters[x] = temp;
}
}
}
}
Thanks in advance for all your help.

Answer 1

My C is a little rusty, but shouldn't the third argument to the fscanf function be an address (like &words and &jumbles)?
