Find the smallest and second smallest element in an array

Here given code implementation process.

//C Program 
//Find the smallest and second smallest element in an array
#include <stdio.h>

#include <limits.h>

void find_smallest(int arr[], int size)
{
	if (size < 2)
	{
		return;
	}
	else
	{
		//Variable which is used to store the result 
		int first = INT_MAX;
		int second = INT_MAX;
		for (int i = 0; i < size; i++)
		{
			//compare the array element values
			if (first > arr[i])
			{
				if (second > first)
				{
					second = first;
				}
				first = arr[i];
			}
			else if (second > arr[i])
			{
				second = arr[i];
			}
		}
		//Display result
		printf("First smallest : %d\n", first);
		printf("Second smallest  : %d\n", second);
