This program is implemented in C++ using Turbo C. Use Graphics.h header file for visual understanding of the algorithm. Graphics.h is the C library which helps to create graphical shapes, like Circle, Rectangles etc.

This knn algorithm program has two classes A and B. Each class has 4 members. This program Get x and y coordinates of the class members in input.

When all members of class A & B are located than enter new member location. Program automatically calculates the distance of new member from the member of both classes.

After calculating and sorting the distances between the members of classes. Put the value of k (which is less than 9 for this program). New member goes into any of these classes with respect to the value of k. For download this knn algorithm program .cpp file Click below.

How this knn algorithm Program component work

You need to have installed Turbo C which have Graphics.h library in working condition. I am sure you clearly understood about the operating system on which it work.

• These for loops take input for class A and Class B members locations. And show circles on that locations.

cout<<"Enter the Class A memebers location"<<endl;
	for (i=0 ; i>A[0][i];
		cout<<"ty-cordinates of member "<<++i<<" ="; 
                i--; cin>>A[1][i];
		x1=A[0][i];
		y1=A[1][i];
		circle(getmaxx()/2+x1, getmaxy()/2-y1, radius);
		clas[j]='A';
	}

cout<<"Enter the Class B memebers location"<<endl;
	setcolor(5);
	for (h=0, j=4 ; h>B[0][h];
		cout<<"ty-cordinates of member "<<++h<<" ="; 
                h--; 		cin>>B[1][h];
		x1=B[0][h];
		y1=B[1][h];
		clas[j]='B';
		circle(getmaxx()/2+x1, getmaxy()/2-y1, radius);
	}

• Take the location of New member which point in the form of circle. After that for loop calculate the distance of New member from the members of other classes (A & B).

cout<<"Enter x-cordinate of New member = "; cin>>x2;
cout<<"Enter y_cordinate of New member = " ; cin>>y2;
circle(getmaxx()/2+x2, getmaxy()/2-y2, 5);

for(j=0, h=0; j<4;h++, j++)
{
	x1=A[0][h];
	y1=A[1][h];
	distance[j]=sqrt((pow((x2-x1), 2.0 ) + pow((y2-y1) , 2.0)) );
}
for(j=4, h=0; j<8;h++, j++)
{
	x1=B[0][h];
	y1=B[1][h];
	distance[j]=sqrt((pow((x2-x1), 2.0 ) + pow((y2-y1) , 2.0)) );
}

• Nested for loop for sorting the distances; which calculated between new member and class members.

int m, l,n;
float key;
	for( m=0; m<8; m++) 		
               for(n=7 ; n>=m+1 ; n--)
			if(distance[n] < distance[n-1])
			{
				int t = distance[n];
				distance[n]= distance[n-1];
				distance[n-1] = t;
				char temp = clas[n];
				clas[n]=clas[n-1];
				clas[n-1]=temp;
			}

• Get the value of K and make decision on the base of its value. Either New member goes into Class A or in Class B. And finally knn algorithm work is done.

cout<< "nEnter value of K = "; cin>>k;
int chk ,a=0,b=0;
	for (chk=0; chk<k; chk++)
	{
		cout<<clas[chk]<<"  ";
		if(clas[chk]=='A')
		{
			a++;
		}
		else if(clas[chk]=='B')
		{
			b++;
		}
	}

cout<<""<<endl; 	if(a>b)
	{
        setcolor(3);
	outtextxy(getmaxx()/2,getmaxy()/2+50,"New Member lies in Class A");
	}
	else if(b>a)
	{
	setcolor(5);
	outtextxy(getmaxx()/2,getmaxy()/2+50,"New Member lies in Class B");
	}

Everyone knows the importance of virtual machine. Virtual machine provides a very good platform to work virtually on windows.

Creating virtual machine is very simple. You can use any operating system like Ubuntu, windows, fedora, Red hat Linux etc. Or any server like mikrotik, windows, ubuntu severs and many others.

After making these virtual machine you can do any experiments on them. For example, you want to learn mikrotik server configuration than you can simply do this on your own system. You can also create ubuntu proxy servers virtually.

Due to these advantages of virtual machine, we need to work on it. So, no more wait just start learning How to create a virtual machine using VMware workstation.

Follow bellow steps to create a virtual machine:

Open VMware Workstation and click on File in the menu bar. Here select Create a New virtual machine or simply press ctrl + n buttons.

1. A new window name “New Virtual Machine Wizard” is appearing. Here you need to select, what type of configuration you want to use. Select Typical if you are new user and press next.
2. There are three options
   • Use first option if operating system/server is on Disk.
   • 2nd for selecting ISO image of the operating system during creation of virtual machine.
   • In 3rd you can create a virtual machine without any operating system. But you need to select an operating system in ISO format, before using this virtual machine.
   

   three methods for how to create a virtual machine   [trickybook.com]

3. In my case, I select second option and browse an iso image of windows 7 from my system. This iso image may be of an operating system or server.
4. In next window you need to select guest operating system type and there version. Select Microsoft windows if your operating system is windows product (like windows 7, 8 or windows server 2008, 2003). Or select Linux if you want to install any Linux distro like (fedora, Ubuntu etc).
5. Next page enter a product key; you need to enter this product key in case of windows product.And select flavor of windows product (professional, home basic, premium etc). Linux products not required product keys. at the end press next.
   
   

   enter a product key and select flavor [trickybook.com]

6. Here you see default name and path for the new virtual machine. You can change name and also the path of the virtual machine if you want. and press next.

7. Set the size of the disk, by default it is 60 GB for windows. Change this to 20 GB or as you like. Select split virtual disk into multiple files option from below. This option provides you help to use virtual machine on any other system.  Just copy the folder which contains the virtual machine files and past on other system which also have Virtual machine software.  And use it.
   
   

   Select disk space and way of saving data [trickybook.com]

8. In next window you can customize hardware, like you can increase or decrease the ram allocation to virtual machine. and finally press finish.

VMware start creating disk. After few seconds, you see operating system installation is start which you want to install on in virtual machine. This installation is similar like normal installation. This procedure requires some time and it depends upon your physical memory allocation. If you allocate more memory than it install quickly .

Personally i like all operating system either Linux, mac or windows. As I check the new features of windows 10, i fell that many changes in these features come from other operating systems like Linux/Mac systems. This thing is really good because this is welcome for Linux/mac users.

These changes are really help for new and also current users of windows operating system. Some of best new windows 10 features are listed below. So, let’s read them.

Return of the Start menu

First best new Windows 10 feature is return of the start menu. Start menu same like start menu of the windows 7.

• Here search bar and all apps available.
• You will find traditional windows desktop apps and also metro apps/universal apps here.
• You can pin your favorite apps at right side of the start menu. These pinned apps can easily unpin from here by right click on it.

Task View

Windows 10 best new feature is Task View for multiple desktops. Task view is a virtual desktop technology. This feature is not new for those who are pretty familiar with Linux/mac operating system. But this thing is definitely new for windows users. The idea behind this feature is to increase the number of desktops. For example we have only one desktop in windows 7 or 8. We open all apps (either desktop or universal apps) on that single desktop. Now in windows 10 you can open more than one desktop and can open different apps on different desktop.

• You can see only those apps which are available on that desktop (which you are currently selected). Other apps are hidden (which are opened on other desktops).
• You can create, view, remove desktop from task view. We can also move open apps from one desktop to other desktop.
• The apps which are opened on other desktops are having a thin line below them in the task bar.
