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 · ...
AIM : TO create a program to implement unary operator overloading
ReplyDeletePROCEDURE :
The unary operators operate on a single operand and following are the examples of Unary operators −
i)The increment (++) and decrement (--) operators.
ii)The unary minus (-) operator.
iii)The logical not (!) operator.
The unary operators operate on the object for which they were called and normally, this operator appears on the left side of the object, as in obj, -obj, and ++obj but sometime they can be used as postfix as well like obj++ or obj--.
PROGRAM :
#include
using namespace std;
class Distance
{
private:
int feet;
int inches;
public:
Distance()
{
feet = 0;
inches = 0;
}
Distance(int f, int i)
{
feet = f;
inches = i;
}
void displayDistance()
{
cout << "F: " << feet << " I:" << inches <<endl;
}
Distance operator- ()
{
feet = -feet;
inches = -inches;
return Distance(feet, inches);
}
};
int main()
{
Distance D1(11, 10), D2(-5, 11);
-D1;
D1.displayDistance();
-D2;
D2.displayDistance();
return 0;
}
Error : 0
Output :
F: -11 I: -10
F: 5 I: 11
Result :
I have successfully done my program.

ReplyDeletePROCEDURE :
Step 1: Start the program.
Step 2: Declare the class.
Step 3: Declare the variables and its member function.
Step 4: Using the function getvalue() to get the two numbers.
Step 5: Define the function operator +() to add two complex numbers.
Step 6: Define the function operator –()to subtract two complex numbers.
Step 7: Define the display function.
Step 8: Declare the class objects obj1,obj2 and result.
Step 9: Call the function getvalue using obj1 and obj2
Step 10: Calculate the value for the object result by calling the function operator + and operator -.
Step 11: Call the display function using obj1 and obj2 and result.
Step 12: Return the values.
Step 13: Stop the program.
PROGRAM :
#include
using namespace std;
class complex
{
int a, b;
public:
void getvalue()
{
cout << "Enter the value of Complex Numbers a,b:";
cin >> a>>b;
}
complex operator+(complex ob)
{
complex t;
t.a = a + ob.a;
t.b = b + ob.b;
return (t);
}
complex operator-(complex ob)
{
complex t;
t.a = a - ob.a;
t.b = b - ob.b;
return (t);
}
void display()
{
cout << a << "+" << b << "i" << "\n";
}
};
int main()
{
complex obj1, obj2, result, result1;
obj1.getvalue();
obj2.getvalue();
result = obj1 + obj2;
result1 = obj1 - obj2;
cout << "Input Values:\n";
obj1.display();
obj2.display();
cout << "Result:";
result.display();
result1.display();
return 0;
}
Error : 0
Output :
Enter the value of Complex Numbers a, b
4
5
Enter the value of Complex Numbers a, b

Input Values
4 + 5i
2 + 2i
Result
6 + 7i
2 + 3i
Result :
I have successfully done my program.

AIM:To show the program of unary operator in c++
ReplyDeletePROCEDURE: In this program declare the class and also declare the variable and its member function.And in this program use the function getsample()to get the two number.The function operator ++ to increment the values and the function -- to decrement the values and atlast call the getsample() and dispsample().
PROGRAM:
#include
using namespace std;
class sample
{
private:
int a;
public:
void getsample(int x)
{
a=x;
}
void dispsample(void)
{
cout<<"value of a is:"<<a;
}
void operator ++(void)
{
a=++a;
}
void operator --(void)
{
a=--a;
}
};
int main()
{
sample obj;
obj.getsample(10);
++obj;
cout<<"After increment -";
obj.dispsample();
cout<<endl;
--obj;
cout<<"After decrement-";
obj.dispsample();
cout<<endl;
return 0;
}
ERROR:0
OUTPUT:After increment-value of a is:11
After decrement-value of b is:10
RESULT:I have done my program successfully.
AIM:-To create a program to implement unary operator overloading.
ReplyDeletePROCEDURE:-Binary operator(operator that operates on two operands) one of the operands should be passed argument to the operator function.
1.Three objects type of complex are created and user is asked to enter the real and imaginary parts for two complex numbers which are stored in object c1.
2.Then statement result=c1 is excuted the statement invokes the operator function.
PROGRAM:-
#include
using namespace std;
class complex
{
int real,imaginary;
public:
complex()
{
}
complex(int a,int b)
{
real=a;
imaginary=b;
}
void operator-();
void display()
{
cout<<"real value:"<<real<<endl;
cout<<"imginary value:"<<imaginary<<endl;
}
};
void complex::operator-()
{
real= -real;
imaginary= -imaginary;
}
int main()
{
complex c1(10,12);
cout<<"real and imaginary value before operation:"<<endl;
c1. display();
-c1;
cout<<"real and imaginary value after operation:"<<endl;
c1.display();
return 0;
}
ERROR:-0
OUTPUT:-
Real and imaginary value before operation:
Real value=10
Imaginary value=12
Real and imaginary value after operation:
Real value=-10
Imaginary value=-12
RESULT:-I have successfully done my program.
