Get code of K Means Clustering with Example in C++ language. This is very simple code with example. Copy this code from here and paste into any compiler and run code.

```#include <iostream>
#include <conio.h>
#include <stdlib.h>

cout << "How many numbers you want to enter: ";
cin >> numbers;

cout << "Enter value of k: ";
cin >> k;

//get numbers
for(int i = 0; i < numbers; i++)
