struct point a;
a.x = 1;
a.y = 2; // C89 (too verbose)
struct point b = { 3, 4 }; // initializer list (struct member order specific)
struct point c = { .x = 5, .y = 6 }; // designated initializer (non struct member order specific)
struct point d = (struct point) { .x = 7, .y = 8 }; // compound literal (cast + designated initialization)
