Write a c++ program to show multiple inheritance and dynamic polymorphism in same program.
INTRODUCTION OF HADOOP & SPARK
INTRODUCTION Hadoop and Apache Spark both are big-data frameworks, but direct comparison of Hadoop and Spark is difficult because they do many of the same things, but are also non-overlapping in some areas. Hadoop is essentially a distributed data infrastructure, It distributes massive data collections across multiple nodes within a cluster of commodity servers, which means you don't need to buy and maintain expensive custom hardware. It also indexes and keeps track of that data, enabling big-data processing and analytics far more effectively than was possible previously. Spark, on the other hand, is a data-processing tool that operates on those distributed data collections; it doesn't do distributed storage Hadoop have many components of modules that work together to create the Hadoop framework. The primary Hadoop framework modules are: · Hadoop Common · ...

ReplyDeleteTo write a c++ program to show multiple inheritance & polymorphism in same program.
Procedure
In this c++ program there are two base classes and one derived class which is showing MULTIPLE INHERITANCE(Here a class can inherit from more than one classes).
There are two Member Functions declared within the base class and are overriden by derived class. These member function are VIRTUAL FUNCTIONS.
This program is for calculating Area for the Length and Breadth given in Integer Type and in Real type(Real numbers).
Here,In main function
For class rec there is one object created which is used to call the member functions of class rec and can also be used to call the member function of its base classes.
Program:
#include
using namespace std;
class value1 //base class 1
{
public:
virtual int area1() //virtual member function1
{
cout<<"For integer values";
}
};
class value2 //base class 2
{
public:
virtual float area2() //virtual member function2
{
cout<<"For real values";
}
};
class rec:public value1,public value2 //derived class
{
public:
int area1(int len,int bth) //member function
{
return(len*bth);
}
float area2(float len,float bth) //member function
{
return(len*bth);
}
};
int main() //main function
{
rec r; //object created
int a,b;
cout<<"enter integer values";
cin>>a>>b;
cout<<"area is:"<>c>>d;
cout<<"area is:"<<r.area2(c,d); //function calling
return 0;
}
Errors
There are no errors found in this program.
Result
Output
Enter integer values
5
8
area is:40
Enter real values
12.68
57.15
area is:724.664

ReplyDeleteAim : To creat a program using multiple inheritance and polymorphism.
ReplyDeleteProcedure :
To creat multiple inheritance, we have to create two base class i.e. area and perimeter and one derived class i.e. rectangle. For polymorphism, we have to do function overriding. In my program i used run time polymorphism or also know as dyna,ic polymorphism.
Program :
#include
using namespace std;
class area
{
public:
int getarea(int l,int b)
{
return l*b;
}
};
class perimeter
{
public:
int getperimeter(int l, int b)
{
return 2*(l+b);
}
};
class rectangle : public area, public perimeter
{
int length;
int breadth;
public:
rectangle()
{
length = 10;
breadth = 15;
}
int area()
{
return area::getarea(length, breadth);
}
int perimeter()
{
return rectangle::getperimeter(length, breadth);
}
};
int main()
{
rectangle rt;
cout <<"area : "<<rt.area() <<endl;
cout <<"perimeter : "<<rt.perimeter()<<endl;
return 0;
}
Output :
Area = 150
Perimeter = 50
Error : 0

AIM:-
ReplyDeleteTo write a c++ program to show multiple inheritance & dynamic polymorphism in same program.
PROCEDURE:-
There are two base classes “odd” and ”even” one derived class(child class)”num”. which is known as MULTIPLE INHERITANCE as it allows child class to inherit from more than one base class.
There are virtual functions used in both base classes which are then overrided in the derived class.
This program is based on finding whether the number is odd or even.
Program:
#include
using namespace std;
class odd
{
public:
virtual int numtype1()
{
cout<<"for odd number";
}
};
class even
{
public:
virtual int numtype2()
{
cout<<"for even number";
}
};
class num:public odd,public even
{
public:
int numtype1(int n1)
{
if(n1%2!=0)
{
cout<<"\nnumber is odd";
}
else
{
cout<<"\nnot odd";
}
}
int numtype2(int n2)
{
if(n2%2==0)
{
cout<<"\nnumber is even";
}
else
{
cout<<"\nnot even";
}
}
};
int main()
{
num b;
int x;
cout<<"enter a number";
cin>>x;
b.numtype1(x);
b.numtype2(x);
return 0;
}
Errors
There are no errors found in this program.
Error=0.
Result
o/p
enter a number
5
Number is odd
Not even
Aim:- to create a c++ program using multiple inheritance and dynamic polymorphism in same program.
ReplyDeleteProcedure:-
Multiple inheritance has two base classes and one derived class.It is a feature of c++ where a class can inherit from more than one class..
When two member functions are declared within a base class and are overridden with the help of a derived class that member function is called as virtual function.
Program:-
#include
using namespace std;
Class student
{
public:
int rno,m1,m2;
public:
virtual int get details ();
{
cout<<"enter the roll no:";
cin>>rno;
cout<<"enter the two marks:";
cin>>m1>>m2;
}
};
Class sports
{
protected:
int sm;
public:
void get details ()
{
cout<<"\n enter the sports marks:";
cin>>sm;
}
};
Class statement: public student,public sports
{
public:
int tot,avg;
void get details ()
{
tot=(m1+m2+sm);
avg=tot/3;
cout<<"\n\n troll no :"<<rno<<"\n\taverage :"<<avg;
}
};
int main
{
statement obj;
obj.get details();
ohh.get sm();
obj.display();
return 0;
}
Output:-
Enter roll no -21
Enter two marks -9,8
Enter sports marks -10
Roll no-21
Total -27
Average -27/3

AIM – Write a program to create multiple inheritance with compile time polymorphism .
ReplyDeletePROCEDURE - In my program I used two base class (as in multiple inheritance we have to use more than one base class). First is monthly and the another is yearly.
After that I made a subclass class , named income which inherits properties of base class (monthly and yearly).
In both base class I used function overloading which is also a compile time polymorphism.
In first I used function salary and in another I used function money.
In main function I give value of each parameters.
#include
using namespace std;
class monthly
{ public:
void salary(int x)
{ cout<<"monthly income of ID - A is:"<< x << endl;
}
void salary(float y)
{ cout<<"monthly income of ID - B is:"<< y << endl;
}
void salary(double z)
{ cout<<"monthly income of ID - C is:"<< z << endl;
}
void salary(int x, float y, double z)
{cout<<"Four months income of ID - A,B and C is:"<< x << "," << y << "," << z << endl;
}
};
class yearly
{ public:
void money(int x)
{ cout<<"yearly income of ID - A is:"<< x << endl;
}
void money(float y)
{ cout<<"yearly income of ID - B is:"<< y << endl;
}
void money(double z)
{ cout<<"yearly income of ID - C is:"<< z << endl;
}
void money(int x, float y, double z)
{cout<<"Five years income of ID - A,B and C is:"<< x << "," << y << "," << z << endl;
}
};
class income : public monthly , public yearly
{
};
int main()
{ income obj1,obj2;
obj1.salary(1000);
obj1.salary(2000);
obj1.salary(3000);
obj1.salary(4000 , 8000 , 12000);
obj2.money(12000);
obj2.money(24000);
obj2.money(36000);
obj2.money(60000 , 120000 , 180000);
return 0;
