Cannot enqueue array value - c

Question

I create a Queue that includes a two dimensional array, the size of every element of that array is 2. An Exception occurs when I enqueue a 2-size array in the queue.
The following is my code:
#include "stdio.h"
#define size 1000
typedef struct Queue {
int *data[2];
int front;
int rear;
}Queue;
void init(Queue *q)
{
q->front=0;
q->rear=0;
}
void Enqueue(Queue *q,int *value)
{
if(q->rear==size)
return ;
q->data[q->rear++]=value;
}
void main()
{
Queue q[1];
init(q);
int a[10][2];
for(int i=0;i<10;i++) {
a[i][0]=i;
a[i][1]=i*2+1;
Enqueue(q,a[i]);
}
}

Answer 1

*I create a Queue that includes a two dimensional array*
No you just create a pointer array in onw dimensional by int *data[2];
If you want create a Quene that include a two demensional array , it will be int data[size][size_anoter]
However, you didn't need I two dimensional . In void Enqueue(Queue *q,int *value) function , you pass the address from a[i] to data[i] . So you only need a big enough pointer array ;\
int * data[size];
Besides , It is better if you can define size as SIZE.

Answer 2

probably, Feel like the following
#include <stdio.h>
#include <stdlib.h>
#define size 1000
typedef struct Queue {
int (**data)[2];
int front;
int rear;
} Queue;
void init(Queue *q){
q->front=0;
q->rear=0;
q->data = malloc(size*sizeof(int (*)[2]));
}
void Enqueue(Queue *q,int (*value)[2]){
if(q->rear==size)
return ;
q->data[q->rear++]=value;
}
int main(){
Queue q[1];
init(q);
int a[10][2];
for(int i=0;i<10;i++) {
a[i][0]=i;
a[i][1]=i*2+1;
Enqueue(q, &a[i]);
}
//printf("%d\n", (*q->data[0])[1]);
return 0;
}

I can see at least a couple of issues:
typedef struct Queue {
int *data[2];
This is not a pointer to a two-dimensional array of ints, which I assume was what was intended. It is an array of two int pointers.
For a 2D array of 1000 entries of arrays with two elements, you probably wanted:
typedef struct Queue {
int data[size][2];
Then, when you call Enqueue(), copy in the array of two ints into the appropriate entry indicated by rear:
void Enqueue(Queue *q,int value[2])
{
if(q->rear==size)
return ;
memcpy(q->data[q->rear], value, sizeof(q->data[q->rear]));
q->rear++;
}
This solution will make a fixed array. If you want the array to be built dynamically it is a little more complicated as you need to malloc/calloc the memory and then free it when done.
