    it depends; if *a points to an existing array of 10 elements, then yes. If not, then you'd need to dynamically allocate space for the 10 elements.

    Code:
    int a[10], *ap = a; // ok ap points to an existing array
    Code:
    int *a = malloc(10 * sizeof(*a)); // allocate space for 10 elements
    ...
    free(a);
