#include<iostream> using namespace std; void f(int n) { if (n == 1 || n == 0) return; else { cout <

Anyone can please explain this? How the output is 14 times Hello? How many times f(n-1) execute & f(n-2)? Explain step by step please!

Inside the function you print 2 times hello. So each call of f(n) produces 2 hello's. I think it is like that: r = return (when n = 1) f(5) / \ f(4) f(3) / \ / \ f(3) f(2) f(2) r / \ f(2) r 7 calls of f(n) -> 14 prints of hello
