1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

Write a program to calculate and print the first 20 elements of this sequence.  Use a 20-element array to perform this task

Answer 1

#include <iostream>
using namespace std;


int main() {
	int counter=0;
    int numbers[20] = {1,1};
	for (int i = 2; i < 20; i++) {
		numbers[i] = numbers[i - 1] + numbers[i - 2];
	}
	cout << "The first 20 elements of Fibonacci sequence:\n";
	for (int i = 0; i < 19; i++) {
		cout << numbers[i] << ", ";
	}
	cout << numbers[19];
	cin>>counter;
    return 0;
