C：数组结构作为结构数组

Question

I was wondering wondering if it was possible to read a struct of arrays as an arry of structs.

eg

typedf struct foo{
    int a[];
    int b[];
    int c[];
}foo_t;

main:
foo_t foo ={.a={11,12,13},.b={21,22,33},.c={31,32,33}};

So foo[0] would contain {11,21,31}, foo[1] would contain {12,22,32} and foo[2] would contain {13,23,33}

any idea?

Answer 1

Why don't you use an array of the struct.

typedef struct foo{
  int a;
  int b;
  int c;
}foo_t;

main:
foo_t foo[] ={{11,21,31}, {12,22,32}, {13,23,33}};

So foo[0] would contain {11,21,31}, foo[1] would contain {12,22,32} and foo[2] would contain {13,23,33}

Answer 2

No, you can't. An array of structs is structurally and semantically different from a struct of arrays.
