Consider the following C declaration

struct {
      short s[5];
      union {
      float y;
      long z;
      } u;
}t;

Assume that objects of the type short, float and long occupy 2 bytes, 4 bytes and 8 bytes, respectively. The memory requirement for variable t, ignoring alignment considerations, is

The following C declarations

struct node{
  int i:
  float j;
};
struct node *s[10];

define s to be
