Write a C++ program to print Fibonacci series of n terms where n is input by the programmer.

Write a C++ program to print Fibonacci series of n terms where n is input by the programmer.

Program Code:

#include <iostream>

using namespace std;

int main()

{

int number;

int number1 = 0;

int number2 = 1; 

int next_number = 0;

cout << "Enter a positive number: ";

cin >> number;

cout<<endl;

// displays the first two numbers of series which is always 0 and 1

cout << "Fibonacci Series: " ;

cout<< number1 << ", " << number2 << ", ";

// now third number of the series is the addition of its previous two number

next_number = number1 + number2;

while(next_number <= number)

{

cout << next_number << ", ";

number1 = number2;

number2 = next_number;

next_number = number1 + number2;

}

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter a positive number: 30

Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21
