Code Array

Move all zeros to the beginning of the array

Here given code implementation process.

// C Program 
// Move all zeros to the beginning of the array 
#include <stdio.h>

//Display elements of given array
void printArray(int arr[], int size)
{
	for (int i = 0; i < size; ++i)
	{
		printf("  %d", arr[i]);
	}
	printf("\n");
}
// Swap the elements of array by given location
void swapElement(int arr[], int front, int tail)
{
	int temp = arr[front];
	arr[front] = arr[tail];
	arr[tail] = temp;
}
// Move all zero elements to front side of given array
void moveZero(int arr[], int size)
{
	// Get first position
	int head = 0;
	// Get last position
	int tail = size - 1;
	// Executes the loop until the value of head variable is less than tail variable
	while (head < tail)
	{
		if (arr[head] == 0)
		{
			// When starting i position zero exist
			head++;
		}
		else
		{
			if (arr[tail] == 0)
			{
				// Swap the array elements
				swapElement(arr, head, tail);
				head++;
				tail--;
			}
			else
			{
				tail--;
			}
		}
	}
}
int main(int argc, char const *argv[])
{
	// Define array of integer elements
	int arr[] = {
		1 , 8 , 12 , 0 , 3 , 1 , 0 , 2 , 0 , 1 , 1 , 0
	};
	// Get the size
	int size = sizeof(arr) / sizeof(arr[0]);
	printf("  Array Element \n");
	printArray(arr, size);
	moveZero(arr, size);
	printf("  After move zero at beginning \n");
	printArray(arr, size);
	return 0;
}
