Count all pairs of given product

Here given code implementation process.

//C Program 
//Count all pairs of given product
#include <stdio.h>

//print the array elements
void display(int arr[], int size)
{
	int i = 0;
	for (i = 0; i < size; i++)
	{
		printf("  %d", arr[i]);
	}
}
//Count all pairs of given product in array
void count_product(int arr[], int size, int product)
{
	int counter = 0;
	for (int i = 0; i < size; ++i)
	{
		for (int j = i + 1; j < size; ++j)
		{
			if (arr[i] * arr[j] == product)
			{
				//When get a new pair
				counter++;
			}
		}
	}
	printf("\n  Pair of product [%d]  is : %d ", product, counter);
}
int main()
{
	//Define array elements
	int arr[] = {
