Question

Write an application program in C++ to implement a class Fibonacci to print Fibonacci series upto N using member function series() .
​

Answer 1

Answer:

Program approach:-

• Using the header file.
• Using the standard namespace I/O.
• Define the main function.
• Display the number of terms.
• Display the Fibonacci series.
• Print the first two numbers.

Explanation:

Program:-

//header file

#include <iostream>

//using namespace

using namespace std;

//main function

int main() {

   int n, s1 = 0, s2 = 1, nextTerm = 0;

//display the number of terms

   cout << "Enter the number of terms: ";

   cin >> n;

//display the Fibonacci series

   cout << "Fibonacci Series: ";

   for (int j = 1; j <= n; ++j) {

       // Prints the first two terms.

       if(j == 1) {

           cout << s1 << ", ";

           continue;

       }

       if(j == 2) {

           cout << s2 << ", ";

           continue;

       }

       nextTerm = s1 + s2;

       s1 = s2;

       s2 = nextTerm;

       

       cout << nextTerm << ", ";

   }
