Issues with string in structure in C codig - c

Question

I have some issues with strings in structure, i think that the problem is strcpy(), but i can't resolve it. My exercise says that i have to write a program that prints the distinct words given as input, sorted in order of frequency of decreasing occurrence and precede each word with its number of occurrences. I thought that scanf could do something wrong so i used fgets() to stdin to take my string from input, but it didnt resolve my problem :(. Here is my code (i haven't yet written the function that prints the words in order of frequency).
/*

*/
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>
#define SIZE 30
#define MAXWORD 5
typedef struct word_dictionary{
char ww[SIZE];
int occ;
} word;
int is_in_bucket(char *str, word data[]){
int j;
for(j=0;j<MAXWORD;j++){
if( strcmp(str,data[j].ww) == 0)
return 1;
}
return 0;
}
void print_bucket(word data[]) {
int i;
for(i=0;i<MAXWORD;i++){
printf("{%d, %s} ", data[i].occ, data[i].ww);
}
printf("\n");
}
void main( int argc, char **argv) {
word bucket[MAXWORD];
char aux[SIZE];
int i;
int x;
int cond;
for(i=0;i<MAXWORD;i++) {
printf("Insert the word you want to save in the data structure: ");
scanf("%s",aux);
cond = is_in_bucket(aux,bucket);
if(cond == 1) {
bucket[i].occ = bucket[i].occ + 1;
memset(aux,0,SIZE);
} else {
strcpy(bucket[i].ww, aux);
bucket[i].occ = 1;
memset(aux,0,SIZE);
}
}
print_bucket(bucket);
// print_occurrences();
return;
}
My terminal output is:
Insert the word you want to save in the data structure: dog
Insert the word you want to save in the data structure: cat
Insert the word you want to save in the data structure: dog
Insert the word you want to save in the data structure: dog
Insert the word you want to save in the data structure: mouse
{1, dog} {1, cat} {-1768437999, } {1, V} {1, mouse}
My expected terminal output should be:
Insert the word you want to save in the data structure: dog
Insert the word you want to save in the data structure: cat
Insert the word you want to save in the data structure: dog
Insert the word you want to save in the data structure: dog
Insert the word you want to save in the data structure: mouse
{3, dog} {1, cat} {1, mouse}

For starters the function main shall have the return type int
int main( int argc, char **argv)
As the function parameters are not used then it is better to declare the function like
int main( void )
The function is_in_bucket does not take into account the number of actual initialized elements in the array bucket. You need to pass this number to the function.
If a word is already present in the array it is not mean that it is stored exactly in the i-th element of the array.
cond = is_in_bucket(aux,bucket);
if(cond == 1){
bucket[i].occ = bucket[i].occ + 1;
memset(aux,0,SIZE);
You need to return form the function is_in_bucket the index of already initialized element or for example -1 otherwise.
Also the function print_bucket shall take into account the actual number of filled elements of the array bucket.
