struct registered {	string title;
	int isbn;

int quantity; float price;

};

C)	3	D)	4

3) Consider the following structure declaration:		3)
struct registered {	string title;
	int isbn;

int quantity; float price;

} chem1, maht3, prog2;

How to initial the title of chem1?

cout << "Enter the title of chem1 " << endl; cin >> chem1.title;

cout << "Enter the title of chem1 " << endl; getline(cin, chem1.title);

cout << "Enter the title of chem1 " << endl;getline(cin, chem1 -> title);

cout << "Enter the title of chem1 " << endl; cin >> prog2.title;

4) Consider the following structure declaration: 4)

struct point { char c; int x; int y;

};

How to initialize the point M (3, 4) and display it as: coordinates of M are 3 and 4 passing the argument by value?

A) void display (point & p)

{ cout << " Coordinates of point " << p.c << " are " << p.x << " and " << p.y << " ";}

int main()

{ point s; s.c = 'M'; s.x = 3; s.y = 4; display(s); system("pause");

return 0;}

B) void display (point * k)

{ cout << " Coordinates of point " << k -> c << " are " << k -> x << " and " << k -> y << " ";}

int main()

{ point s; s.c = 'M'; s.x = 3; s.y = 8; display(&s); system("pause");

return 0;}

void display (point * k)

{ cout << " Coordinates of point " << (*k).c << " are " << (*k).x << " and " << (*k).y << " ";}

int main()

{ point s; s.c = 'M'; s.x = 3; s.y = 9; display(&s); system("pause");

return 0;}

D) void display (point p)

{ cout << " Coordinates of point " << p.c << " are " << p.x << " and " << p.y << " ";}

int main()

{ point s; s.c = 'M'; s.x = 3; s.y = 4; display(s); system("pause");

return 0;}

5)	struct point {		char c;				5)
		int x;
		int y; };
	void display (point * k)
	{ cout << " Coordinates of point " << (*k).c				<< " are " << (*k).x		<< " and " <<

	int main()
	{ point s; s.c = 'M'; s.x = 3; s.y = 4; display(&s);
	system("pause");
	return 0;}
	In the code snippet above, the structure point M is initialized (3, 4) and
	displayed (as: coordinates of M are 3 and 4) passing the argument by
	A)	value			B)	reference
	C)	address			D)	void
6)		struct point {char c; int x;		int y; };			6)
	void display (point * k)
	{ cout << " Coordinates of point " << k -> c				<< " are " << k -> x		<< " and " << k ->
	y << " ";}
	int main()
	{ point s; s.c = 'M'; s.x = 3; s.y = 4; display(&s);
	system("pause");
	return 0;}
	In the code snippet above, the structure point M is initialized (3, 4) and
	displayed (as: coordinates of M are 3 and 4) passing the argument by
	A)	value			B)	reference
	C)	address			D)	void
7)	struct point { char c;						7)
		int x;
		int y; };
	void display (point & p)
	{ cout << " Coordinates of point " << p.c << " are " << p.x << " and " << p.y << "
	";}
	int main()
	{ point s; s.c = 'M'; s.x = 3; s.y = 4; display(s);
	system("pause");
	return 0;}
	In the code snippet above, the structure point M is initialized (3, 4) and
	displayed (as: coordinates of M are 3 and 4) passing the argument by

8) Consider the following code:

8)

struct song { string singer; string album; int year; float price; } Thriller;

song *psong; psong = &Thriller; string mystr;

What is psong in the snippet above?

A)	a variable	B)	a pointer pointing to singer
C)	a pointer pointing to album	D)	a pointer pointing to Thriller
9) When initializing the members of this structure using pointer, which of the following format do				9)
you advise?

cin >> Thriller.year;

getline (cin, mystr);

(stringstream) mystr >> psong -> year;

cin >> year;

getline (cin, Thriller.year)

SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.

10)	What is the difference between these two expressions:	10)
	expression 1: psong -> year
	expression2: (*psong).year
TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.
11)	The header file needed to use getline ()is	11)
12)	Thre header file to use stringstream is	12)
