Data are not stacking in the queue - c

Question

I have made a queue of nodes to store the data.
And the data should be implemented through file I/O.
In .txt file:
"Name1"
"Birthday1 (month date)"
"Genre1"
"Name2"
"Birthday2 (month date)"
"Genre2"
(above form is repeated)
Whenever I try to run through the code, it shows some strange characters for Name, Genre, and Birthday.
Also, same lines are repeated for 14 times.
I guess the problem has to do with data_in function.
What is the problem, and how can I fix it?
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct node {
char *name, *genre;
int month, date;
struct Node *next;
}Node;
typedef struct Queue {
Node *front;
Node *rear;
int count;
}Queue;
void queue_init(Queue *queue) {
//Initializing needed in order to use the queue
queue->front = queue->rear = NULL;
queue->count = 0;
}
int isEmpty(Queue *queue) {
//Check whehter the queue is empty or not
return (queue->count == 0);
}
void display_node(Node *node) {
printf("\nName: %s", node->name);
printf("\nFavorite Genre: %s", node->genre);
printf("\nBirthday: %d / %d", node->month, node->date);
printf("\n");
}
void data_in(Queue *queue) {
Node *now = (Node *)malloc(sizeof(Node));
FILE *f;
f = fopen("C:\\Users\\brain\\Desktop\\School\\2-2 GWU\\Data Structures and Algorithm\\LAB\\Lab Assignment\\Lab Assignment 3.txt", "r");
for(int i = 0; i < 14; i++) {
char n[100], g[100];
fscanf(f, "%s", &n);
fscanf(f, "%d %d", &now->month, &now->date);
fscanf(f, "%s", &g);
fgets(f);
now->name = (char *)malloc(sizeof(char)*strlen(n));
now->genre = (char *)malloc(sizeof(char)*strlen(g));
now->name = n;
now->genre = g;
if (isEmpty(queue))
queue->front = now;
else
queue->rear->next = now;
queue->rear = now;
queue->count++;
}
fclose(f);
}
void search(Queue *queue) {
Node *now = queue->front;
char c[100], check[100];
int ch, cnt = 0;
printf("Which section do you want to search? (Genre or Month): ");
scanf("%s", &c);
if (strcmp(c, "Genre") == 0) {
printf("Type the genre: ");
scanf("%s", &check);
for (int i = 0; i < queue->count; i++) {
if (now != NULL) {
if (strcmp(now->genre, check)) {
display_node(now);
now = now->next;
cnt = 1;
}
}
}
if (cnt == 0) printf("\n.....No results found...");
}
else if (strcmp(c, "Month") == 0) {
printf("Type month as an integer: ");
scanf("%d", &ch);
for (int j = 0; j < queue->count; j++) {
if (now != NULL) {
if (now->month == ch) {
display_node(now);
now = now->next;
cnt = 1;
}
}
}
if (cnt == 0) printf("\n.....No results found...");
}
}
int main(void) {
int check = 1;
Queue DSA;
queue_init(&DSA);
data_in(&DSA);
while (check == 1) {
search(&DSA);
printf("\nDo you want to continue searching? (1 or 0): ");
scanf("%d", &check);
printf("\n============================================================\n");
}
system("pause");
return 0;

These two lines are definitely NOT what you want:
fscanf(f, "%s", &n);
fscanf(f, "%s", &g);
they should read:
fscanf(f, "%s", n);
fscanf(f, "%s", g);
(notice the removed &).
Also, the next line:
fscanf(f, "%d %d", &now->month, &now->date);
should have a space as the first character of the format string:
fscanf(f, " %d %d", &now->month, &now->date);
