For the life of me I can't figure out the proper syntax for creating an array of structures in C. I tried this:

struct foo {
    int x;
    int y;
} foo[][] = {

    {
        { 1, 2 },
        { 4, 5 },
        { -1, -1 }
    },

    {
        { 55, 44 }
        { 100, 200 },
    }
};

So for example foo[1][0].x == 100, foo[0][1].y == 5, etc. But GCC spits out a lot of errors.

If anyone could provide the proper syntax that'd be great.

EDIT: Okay, I tried this:

struct foo {
     const char *x;
     int y;
};

struct foo bar[2][] = {

     {
      { "A", 1 },
      { "B", 2 },
      { NULL, -1 },
     },

     {
      { "AA", 11 },
      { "BB", 22 },
      { NULL, -1 },
     },

     {
      { "ZZ", 11 },
      { "YY", 22 },
      { NULL, -1 },
     },

     {
      { "XX", 11 },
      { "UU", 22 },
      { NULL, -1 },
     },
};

But GCC gives me "elements of array bar have incomplete type" and "excess elements in array initializer".
