Chapter 3.9, Problem 3.45PP

A.

Explanation of Solution

Byte offsets of all structure fields:

Field	a	b	c	d	e	f	g	h
Size	8	2	8	1	4	1	8	4
Offset	0	8	16	24	28	32	40	48

Explanation:

• The variable “a” denotes a “char*” type...

B.

Explanation of Solution

Total size of structure:

• The variable “a” denotes a “char*” type. It takes 8 bytes.
• The variable “b” denotes a “short” type. It takes 2 bytes.
• The variable “c” denotes a “double” type. It takes 8 bytes.
• The variable “d” denotes a “char” type. It takes 1 bytes.
• The variable “e” denotes a “float” type...

C.

{

char *a;

double c;

long g;

float e;
