Write a C++ to read and display information about employees and managers. Employee is a class that contains employee number, name, address ad department. Manager class contains all information of the employee class and a list of employees working under a manager. 

Differentiate between public and protected visibility in context of Object Oriented Programming giving suitable examples for each.

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.

When does ambiguity arise in multiple inheritance? How can one resolve it? What are virtual base classes? What is their significance?

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

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;

}

What is inheritance? Discuss its various forms.

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

Create the following class hierarchy in C⁺⁺.

A class One with data members int a and char b inherits from another class Two with data members float f and int x. Write definitions for One and Two for the following situations:

(i) Objects of both the classes are able to access all the data members of both the classes.

(ii) Only the members of class One can access all the data members of both the classes.
