Move all negative elements to end in c

C program for Move all negative elements to end. Here more solutions.

// Include header file
#include <stdio.h>
#include <stdlib.h>
// C program for
// Move all negative elements at the end of array

// Display array elements
void display(int arr[], int n)
{
	for (int i = 0; i < n; i++)
	{
		printf("  %d", arr[i]);
	}
	printf("\n");
}
// Swap the given array elements
void swap(int arr[], int start, int end)
{
	int temp = arr[start];
	arr[start] = arr[end];
	arr[end] = temp;
}
// Method which is move negative elements
void moveNegative(int arr[], int n)
{
	// first index
	int i = 0;
	// last index
	int j = n - 1;
	while (i < j)
	{
		if (arr[i] < 0 && arr[j] >= 0)
		{
			// When [i] index are have negative value 
			// And [j] is positive then swapping elements values
			swap(arr, i, j);
			// Modified index
			i++;
			j--;
		}
		else if (arr[i] >= 0)
		{
			// When element of [i] is not negative
			i++;
		}
		else
		{
			j--;
		}
	}
}
int main()
{
	
	// Array which are containing positive and negative values
	int arr[] = {
		1 , -1 , 3 , 2 , -7 , -5 , 11 , 6
	};
	int n = sizeof(arr) / sizeof(arr[0]);
	printf("Before Arrange : \n");
	// Before move element
	display(arr, n);
	// Move negative elements
	moveNegative(arr, n);
	// After arrange
	printf("After Arrange : \n");
	// After move element
	display(arr, n);
  	return 0;
}

Output

Before Arrange :
  1  -1  3  2  -7  -5  11  6
After Arrange :
  1  6  3  2  11  -5  -7  -1
