Write a program to print the fibonacci series sum upto a particular no. using recursion.

#include <iostream>

int sum = 0;

void Fib(int cnt, int last_num, int cur_num)
{
	if (cnt == 0)
		return;

	sum += cur_num;
	std::cout << cur_num << " ";
	Fib(--cnt, cur_num, last_num + cur_num);
}

int main()
{
	Fib(1, 0, 1);
	std::cout << " = " << sum;

	return 0;
}
