a tricky bug: lost items

#define LEN 4
int tape[LEN] = {6640, 5600, 3650, 0};

void search(int target) {
    queue_t q1;

    for(int i=0; i< LEN; i++) {
        enqueue(&q1, (void*)tape[i]); // this is hacky
    }

        if ((int)tmp == target) {
            printf("FOUND!\n");
            return;
        }
    }
    printf("NOT FOUND!\n");

int main() {
