C在数组初始化中初始化指向数组的指针

Question

我需要初始化这个结构的数组：

struct a {

   int *a;
   int *b;
   int count;
};

我的代码看起来像这样;

struct a[] = 
{
  {{1,2},{3,4}, 2},
  {{1},{3}, 1}
};

当程序试图访问字段的第一个元素时，这将编译但是段错误。

Answer 1

struct a a[] = 
{
  {(int[]){1,2},(int[]){3,4}, 2},
  {(int[]){1},(int[]){3}, 1}
};

Answer 2

你应该使用类似的东西（添加到BLUEPIXY＆＃39;答案）

static int arr1[] = {1, 2};
static int arr2[] = {3, 4};
static int arr3[] = {1};
static int arr4[] = {3};

struct a a[] = 
{
  {arr1, arr2, 2},
  {arr3, arr4, 1}
};
