In C++, Generate Next Fibonacci Series Using Call by Reference To Function

#include<iostream>

using namespace std;

void nextFibo(int &f1, int &f2) {
	int f3 = f1 + f2;
	f1 = f2;
	f2 = f3;
}

int main(){
	int f1 = 1, f2 = 1;
	for(int i = 1; 10 >= i; i++){
		cout << f1 << ' ';
		nextFibo(f1, f2);
	}
	cout << endl;
	return 0;
}
