quick test that templated harmonic mean works with int and float

harmonicMean.cpp

// CPP program to find harmonic mean of numbers.
#include <bits/stdc++.h>
using namespace std;

template <typename T>
float harmonicMean(T arr[], int n){
	// Declare sum variables and initialize
	// with zero.
	float sum = 0;
	for (int i = 0; i < n; i++)
		sum = sum + (float)1 / arr[i];

	return (float)n/sum;
}

int main()
{
	float arr_f[] = { 13., 14., 14., 15., 16. };
	int arr_i[] =  { 13, 14, 14, 15, 16 };
	int n_f = sizeof(arr_f) / sizeof(arr_f[0]);
	int n_i = sizeof(arr_i) / sizeof(arr_i[0]);
	cout << harmonicMean(arr_f, n_f);
	cout << "\n";
	cout << harmonicMean(arr_i, n_i);
	return 0;
