Chapter 10, Problem 10.5E

(a)

Program Plan Intro

Create a Structure inventory which contains the following:

• A character array partName[30]
• An integer partNumber,
• A floating point price
• An integer stock
• An integer reorder.

Explanation of Solution

Explanation:

A structure is a user defined data type which contains related variables which have same name.

Following syntax is used to create a structure with a keyword struct:

struct <structure name>
{
variable 1;
variable 2;
---;
};

Structure named Inventory with the given variables is defined as follows:

struct Inventory
{
char partName[30];
int partNumber;
float pointprice;
int stock;
 int reorder;
};

(b)

Program Plan Intro

Define the union data containing char c, short s, long b, float f and double d.

Explanation of Solution

Explanation:

Union is a user defined data type which contains related variables just like structure which uses same data space for its variable.

Following syntax is used to create an Union data type:

union <union name>
{
variable 1;
variable 2;
---;
};

Union named data which contains char c, short s, long b, float f and double d is defined as follows:

union data
{
char c;
short s;
long b;
float f;
double d;
};

(c)

Program Plan Intro

Create a structure called address that contains character arrays

• streetAddress[ 25]
• city[ 20 ]
• state[ 3]
• zipCode[ 6].

Explanation of Solution

Explanation:

A structure is a derived defined data type which contains related variables which have same name.

Following syntax is used to create a structure with a keyword struct:

struct <structure name>
{
variable 1;
variable 2;
---;
};

Structure with the name address containing character arrays is defined as follows:

struct address
{
char streetAddress[25];
char city[20];
char state[3];
char zipCode[6];
};

(d)

Program Plan Intro

Create a structure student that contains the following :

• An character array firstName[15]
• An character array lastName[15]
• variable homeAddress of type struct address.

Explanation of Solution

Given Information

Structure named address as follows:

struct address
{
char streetAddress[25];
char city[20];
char state[3];
char zipCode[6];
};

Explanation:

A structure is a derived defined data type which contains related variables which have same name but each variable in the structure has its own data space.

Keyword struct is used to create a structure as follows:

struct <structure name>
{
variable 1;
variable 2;
---;
};

Structures can be used to declare variable which can access variables of the structure with the use of following syntax:

struct <structure_name><variable_name>;

Structure name Student which contains a structure

A structure student that contains the variable homeAddress of type struct address along with character arrays firstName and lastName is defined as follows:

struct student
{
char firstName[15]; 
char lastName[15];
struct address homeAddress;
};

(e)

Program Plan Intro

Create a structure test which contains a 16 bit fields with widths of 1 bit. The names of the bit fields are the letters a to p.

Explanation of Solution

Explanation:

Bit fields can be defined in the structure which enables user to specify the number of bits a unsigned or int member of variable can store.

Bit fields are defined with the following syntax:

<data type> <bit-field name> <number of bits>

A structure test which contains a 16 bit fields with widths of 1 bit is defined as follows:

struct test
{
     unsigned int a : 1;
     unsigned int b : 1;
     unsigned int c : 1;
     unsigned int d : 1;
     unsigned int e : 1;
     unsigned int f : 1;
     unsigned int g : 1;
     unsigned int h : 1;
     unsigned int i : 1;
     unsigned int j : 1;
     unsigned int k : 1;
     unsigned int l : 1;
     unsigned int m : 1;
     unsigned int n : 1;
     unsigned int o : 1;
     unsigned int p : 1;
};
