# 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``````
