13. Assuming that bit-fields are accommodated from right to left and word size is 16-bits
Consider the declaration
static struct
  {
 unsigned a : 5;
 unsigned b : 5;
  unsigned c : 5;
  unsigned d : 5;
  } v = (1, 2, 3, 4);
information about d will be in the

14. Assuming that bit-fields are accommodated from right to left and word size is 16-bits
Consider the declaration
static struct {
  unsigned a : 5;
  unsigned b : 5;
  unsigned c : 5;
  unsigned d : 5; } v = (1, 2, 3, 4);
If the declaration unsigned c : 5; is replaced by unsigned : 6;
then,

15. Assuming that bit-fields are accommodated from right to left and word size is 16-bits
Consider the declaration
static struct {
&emsp: unsigned a : 5;
&emsp: unsigned b : 5;
&emsp: unsigned c : 5;
&emsp: unsigned d : 5;
&emsp: } v = (1, 2, 3, 4);
Consider the declaration
struct wer {
&emsp: unsigned a : 5;
&emsp: unsigned : 0;
&emsp: unsigned b : 3;
&emsp: unsigned : 0;
&emsp: unsigned c : 2 ;
&emsp: unsigned : 0 ;
&emsp: } v;
The storage needed for v is
