What I'm trying to do is to print my two-dimensional array but i'm lost. The first function is running perfect, the problem is the second or maybe the way I'm passing it to the "Print" function.

#include <stdio.h>
#include <stdlib.h>

#define ROW 2
#define COL 2


//Memory allocation and values input
void func(int **arr)
{
    int i, j;

arr = (int**)calloc(ROW,sizeof(int*));
    for(i=0; i < ROW; i++)
        arr[i] = (int*)calloc(COL,sizeof(int));

    printf("Input: \n");
    for(i=0; i<ROW; i++)
        for(j=0; j<COL; j++)
            scanf_s("%d", &arr[i][j]);
}
//This is where the problem begins or maybe it's in the main

void print(int **arr)
{
int i, j;
for(i=0; i<ROW; i++)
{
        for(j=0; j<COL; j++)
            printf("%5d", arr[i][j]);
                printf("\n");
}
}

void main()
{
int *arr;
func(&arr); 
print(&arr); //maybe I'm not passing the arr right ?
}
