Different way to access array elements

Do you know there are many ways to access the elements of array.
int Num[10];
for(int i=0;i<10;i++)
    printf("%d%d%d%d",Num[i],i[Num],*(Num+i),*(i+Num));
Here all the format will give the same result that is every element of Array.

Malloc and Calloc

Difference between Malloc() and Calloc()
1. malloc() takes one argument while calloc() takes two argument
2. malloc() does not initialize the allocated memory while calloc allocated memory intialized with 0.
3. Both are used for dynamic memory allocation.
4. malloc is faster than calloc
5.Example: int *p=(int *)malloc(sizeof(int));
                   int *p=(int *)calloc(10,sizeof(int));
