Answer the questions (i) to (iv) based on the following: 

class FaceToFace

{

char CenterCode[10];

public:

void Input( );void Output( );

};

class Online

{

char website[50];

public:

void SiteIn( ); 

void SiteOut( );

};

class Training: public FaceToFace, private online

{ 

long Tcode; 

loat charge;

int period;

public:

void Register( );

void show( );

};

(i) Which type of inheritance is shown in the above example?

(ii) Write names of all the member functions accessible from Show( ) function of class Training.

(iii) Write name of all the member accessible through an object of class Training.

(iv) Is the function Output( ) accessible inside the function SiteOut( )? Justify your answer?

Assume a class Derv derived from a base class Base. Both classes contain a member function func() that takes no arguments. Write the definition for a member function of Derv that calls both the func()s.

Imagine a publishing company that markets both books and audio-cassette versions of its works. Create a class publication that stores the title (a string) ad price (type float) of a publication. From this class derive two classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of these three classes should have a getdata() function to get its data from the user at the keyboard, and a putdata() function to display its data.

Write a main() program to test the book and tape classes by creating instances of them, asking the user to fill in their data with getdata(), and then displaying the data with putdata().

Consider the following and answer the questions give below: class MNC

{

char Cname[25];  //Compay name

protected:

char Hoffice[25];  //Head office

public:

MNC();

char Country[25];

void EnterData();

void DisplayData();

};

class Branch:public

MNC 

{  long NOE //Number of employees

char Ctry[25];  //Country

protected:

void Association();

public:

Branch();

void Add();

void Show();

};

class Outlet:public Branch

{

char State[25];

public: Outlet();

void Enter();

void Output();

};

(i) Which class’ constructor will be called first at the time of declaration of an object of class Outlet?

(ii) How many bytes does a object belonging to class Outlet require?

(iii) Name the member function(s), which are accessed from the object(s) of class Outlet.

(iv) Name the data member(s), which are accessible from the object(s) of class Branch.

What is inheritance? Discuss its various forms.

Discuss a situation in which the private derivation will be more appropriate as compared to public derivation

Modify the program 2 of Type C to include constructors for the three classes.

Given the definition of following two classes. Write the constructor definition for both classes.

class Alpha {

int a;

float b;

char c;

public

………. //constructor definition

// has to become here :

};

class Beta:public Alpha {

public:

……..

//constructor definition

};

What will be the output of the following program? 

#include<iostream.h>

class Student

{

public:

Student (char pname[]=” “)

{

strcpy(name,pname);

average=semesterHours=0;

}

void addCourse(int hours,float grade)

{

average=(semesterHours*average+grade); semesterHours+=hours;

average=semesterHours;

}

int hours()

{ return semesterHours; }

float gpa()

{ return average;

}

protected:

char name[40];

int semesterHours;

float average;

};

class GradStudent:public Student

{

public:

GradStudent(char pname[]=” “):Student(pname)

{ qual_grade=0;

}

int qualifier()

{ return qual_grade; }

protected:

int qual_grade;

};

int main() { Student commerce(“Saurabh 7/.”); 

GradStudent gs;

commerce.addCourse(4,2.5);

gs.addCourse(4,3.0);

return 0;

}
