c array convert to pointer and convert pointer to array

//Convert array to pointer
int* arrayPointer7()
{
    static int arr[100];
    for(int i=0;i<100;i++)
    {
        arr[i]=i*i*i*i;
    }

    int *p;
    p=arr;
}

//retrieve array data from pointer via for loop
void arr8()
{
    int *p=arrayPointer7();
    for(int i=0;i<100;i++)
    {
        printf("I=%d\n",*(p+i));
    }
}

1.When convert array to pointer.Declare int pointer at first;

2.Assgin the array to pointer directly.

3.When retrieve array data from pointer;

4.Print pointer data via *(p+i)  loop.
