# Write a recursive function to obtain the first 25 numbers of a Fibonacci sequence.

## Recursive function first 25 numbers of a Fibonacci sequence.

**Object:** Write a recursive function to obtain the first 25 numbers of a Fibonacci sequence. In a Fibonacci sequence the sum of two successive terms gives the third term. Following are the first few terms of the Fibonacci sequence: 1 1 2 3 5 8 13 21 34 55 89…

## Code:

**#include<iostream>**

**#include<conio.h>**

**using namespace std;**

**int fab(int n);**

**void main()**

**{**

** int num,i=0;**

** cout<<“Enter Any Number: “;**

** cin>>num;**

** while (i<=num)**

** {**

** cout<<” “<<fab(i);**

** i++;**

** }**

** getch();**

**}**

**int fab(int n)**

**{**

** if(n==0||n==1)**

** {**

** return n;**

** }**

** else**

** {**

** return((fab(n-1)+fab(n-2)));**

** }**

**}**

#include<iostream> #include<conio.h> using namespace std; int fab(int n); void main() { int num,i=0; cout<<"Enter Any Number: "; cin>>num; while (i<=num) { cout<<" "<<fab(i); i++; } getch(); } int fab(int n) { if(n==0||n==1) { return n; } else { return((fab(n-1)+fab(n-2))); } }
