Answer to Question #345501 in C++ for Umi

Question

Consider a situation that a user wants to print first n (any value, e.g. first 10) numbers of Fibonacci series.

You need to implement a program that gets a number from user and prints first n Fibonacci series

numbers. Write a function for this purpose that prints Fibonacci series recursively. This function should

accept a number in parameter and then print n number of elements of Fibonacci series

Answer 1

#include <iostream>
using namespace std;
void printFibonacciNumbers(int n)
{
    int f1 = 0, f2 = 1, i;
    if (n < 1)
        return;
    cout << f1 << " ";
    for (i = 1; i < n; i++) {
        cout << f2 << " ";
        int next = f1 + f2;
        f1 = f2;
        f2 = next;
    }
}
int main() {
    int n;
    cout<<"Enter the number of elements of Fibonacci series to print: ";
    cin>>n;
    printFibonacciNumbers(n);
    return 0;
}
