Programming Using C Quiz 3 Name: 1. [50 p ] Consider the following declaration: typedef struct { enum {RECTANGLE, CIRCLE} shape_kind; struct point center; union { struct { double height, width; } rectangle; struct { double radius; } circle; } u; } Shape; Shape s, *p; (a) [5 p ] Write an appropriate declaration for point, which represents the coordinates of a point in 2D. Indicate which of the following statements are legal, and show how to repair the ones that aren’t (b) [5 p ] s.shape kind = RECTANGLE (c) [5 p ] printf(“%s”, s.shape kind); (d) [5 p ] s.center.x = 10; (e) [5 p ] s.height = 25; (f) [5 p ] s.u.circle = 5; (g) [5 p ] p = malloc(sizeof(union u)); (h) [5 p ] p.shape kind = CIRCLE; (i) [5 p ] p.center = (*s).center; (j) [5 p ] free(p); p = &s; 1
