4. Suppose that the following declarations are in effect:

struct point {int x, y; };
struct rectangle { struct point upper_left, lower_right; };
struct rectangle *p;

Assume that we want p to point to a rectangle structure whose upper left corner is at (10, 25), and whose lower right corner is at (20, 15). Write a series of statements that allocate such a structure and initialize it as indicated.

struct rectangle rect = { { 10, 25 }, { 20, 15 } };
p = ▭

5. Suppose that f and p are declared as follows:

struct {
	union {
		char a, b;
		int c;
	} d;
	int e[5];
} f, *p = &f;
