Coding:

#include<iostream.h>
#include<stdio.h>
#include<conio.h>
class Person
{
   char Name[20];
   int Age;
public:
  void getData()
  {
    cout<<"Enter Person Name:";
    gets(Name);
    cout<<"Enter Person Age:";
    cin>>Age;
  }
  void putData()
  {
   cout<<"\n\nDetails About Eldest Person as follows:";
   cout<<"\nName="<<Name<<"\nAge="<<Age;
  }
  Person &Compare(Person &p1)
  {
   if(p1.Age>this->Age)
   return p1;
   return *this;
  }
};








void main()
{
  clrscr(); Person x,y,z;
  x.getData();
  y.getData();
  z=x.Compare(y);
  z.putData();

Create two classes DM and DB which store the value of distances. DM stores distances in metres and centimeters and DB in feet and inches.

 
Write  a program that can read values for the class  objects and add one object DM with another object of DB. Use a Friend Function to carry out  the addition operation. The object that stores the results may be a DM object or DB object, depending on the units in which the

Write a program to test your class.

 
Define a class named Student, create following members in it: Data Members: student_name, rollno, class (BCA/MCA), semester, sub1_marks,sub2_marks, sub3_marks,  total marks, average, percentage.                                   
          Member Functions: 
To enter the information of a student. 
To calculate his/her total, average, percentage.
To display the result.  

 Write a program to test your class.
