C結構初始化（整數和整數值的數組）

Question

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

我應該如何初始化結構中的元素？

Answer 1

例如

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

要么

struct setArray s;

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

要么

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

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