DS-LAB(FIBO SERIES) EXP-4

Fibonacci Series Algorithm:

• Start
• Declare variables i, a,b , show
• Initialize the variables, a=0, b=1, and show =0
• Enter the number of terms of Fibonacci series to be printed
• Print First two terms of series
• Use loop for the following steps
  -> show=a+b
  -> a=b
  -> b=show
  -> increase value of i each time by 1
  -> print the value of show
• End

Fibonacci Series Flowchart:

#include <iostream>
using namespace std;

int main() {
    int n, firstTerm = 1, secondTerm = 1, nextTerm;
    cout << "Enter number of terms: ";
    cin >> n;

    cout << "Fibonacci Series: " << firstTerm << " + " << secondTerm << " + ";
    for (int i = 1; i <= n-2; ++i) {
        nextTerm = firstTerm + secondTerm;
        cout << nextTerm << " + ";
        firstTerm = secondTerm;
        secondTerm = nextTerm;
    }
    return 0;
