# Fibonacci series program

#### Fibonacci series in c

``` #include<stdio.h> #include<conio.h> void main() { int a=0,b=1,s=0,n; printf("Enter the number of elements \n"); scanf("%d",&n); printf("%d %d ",a,b); for(int i=2;i<n;i++) { s=a+b; printf("%d ",s); a=b; b=s; } getch(); } ```

#### Output

```Enter the number of elements 7 0 1 1 2 3 5 8 ```

#### Fibonacci series in c++

``` #include<iostream> #include<conio.h> using namespace std; class FibonacciSeries { public: void show(int n) { int a=0,b=1,s=0; cout<<a<<" "<<b<<" "; for(int i=2;i<n;i++) { s=a+b; cout<<s<<" "; a=b; b=s; } } }; void main() { int n; FibonacciSeries f; printf("Enter the number of elements \n"); scanf("%d",&n); f.show(n); getch(); } ```

#### Output

```Enter the number of elements 8 0 1 1 2 3 5 8 13 ```

#### Fibonacci series in c#

``` using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace FibonacciSeriesProject { class FibonacciSeries { public void show(int n) { int a = 0, b = 1, s = 0; Console.Write(a + " " + b + " "); for (int i = 2; i < n; i++) { s = a + b; Console.Write(s + " "); a = b; b = s; } } static void Main(string[] args) { FibonacciSeries fs = new FibonacciSeries(); Console.WriteLine("Enter the number of elements"); int input = Convert.ToInt32(Console.ReadLine()); fs.show(input); Console.ReadLine(); } } } ```

#### Output

```Enter the number of elements 12 0 1 1 2 3 5 8 13 21 34 55 89 ```

#### Fibonacci series in java

``` import java.util.*; class FibonacciSeries { public void show(int n) { int a = 0, b = 1, s = 0; System.out.print(a + " " + b + " "); for (int i = 2; i < n; i++) { s = a + b; System.out.print(s + " "); a = b; b = s; } } } class examples { public static void main(String[] args) { FibonacciSeries fs=new FibonacciSeries(); Scanner sc=new Scanner(System.in); System.out.println("Enter the number of elements"); int input=sc.nextInt(); fs.show(input); } } ```

#### Output

```Enter the number of elements 13 0 1 1 2 3 5 8 13 21 34 55 89 144 ```
