Convert hectare to square kilometer

Here given code implementation process.

//C Program 
//Convert hectare to square kilometer
#include <stdio.h>
 //Find the square kilometer of given hectare
void hectare_to_square_km(double hectare)
{
	// Calculate square kilometer by using hectare
	// Formula : (hectare / 100)
	double square_km = (hectare / 100);
	printf("[%lf] Hectare is equal to [%lf] Square Kilometer \n", hectare, square_km);
}
int main()
{
	//Simple test
	hectare_to_square_km(1);
	hectare_to_square_km(2021);
	hectare_to_square_km(1500.6);
	return 0;
}

Output
