Array question...

I don''t think you can do that. You could write a function that takes a pointer to your var and 16 values...

Stuff(&b.b, 0,0,0,0,
            1,1,0,0,
            0,0,1,1,
            0,0,1,0);

 

You could memcpy from a linear array to your structure. Arrays are guaranteed to be contiguous regions of memory. You could even make it easier by using a union to simultaneously define the struct as both a 2D and linear array:

struct A
{
  union
  {
    int l[16];
    int b[4][4];
  };
}; 

You can now do this:

A b;
int data[] = {0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1};
memcpy(b.l, data, 16 * sizeof(int));
