C Structure initialization (Array of integers and an integer value)

Question

#define MAX 10
struct setArray
{
    int item[MAX];
    int count;
};
typedef struct setArray *BitSet;

how should I initialize the elements in the structure?

Aside: 1) typedef struct setArray *BitSet; though legal, is frowned upon in some style guides: Suggest avoid (exceptions exists) creating typedef of pointers. Instead typedef struct setArray BitSet; BitSet *p = malloc(sizeof *p); 2) int for an array size counter is not as portable as size_t count. — chux

For example

struct setArray s = { { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }, MAX };

Or

struct setArray s;

for ( int i = 0; i < MAX; i++ ) s.item[i] = i;
s.count = MAX;

Or

BitSet p = malloc( sizeof( *p ) );

for ( int i = 0; i < MAX; i++ ) p->item[i] = i;
p->count = MAX;
