Question

Construct an algorithm to print the first 20 numbers in the Fibonacci series (in mathematics) thanks

Answer 1

Answer:

0+1=1

1+1=2

1+2=3

2+3=5

3+5=8

5+8=13

Explanation:

// C++ program to print

// first n Fibonacci numbers

#include <bits/stdc++.h>

using namespace std;

 

// Function to print

// first n Fibonacci Numbers

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;

   }

}

 

// Driver Code

int main()

{

   printFibonacciNumbers(7);

   return 0;

}
