# Fibonacci Series using Recursive function

Write a C++ Program for Fibonacci Series using Recursive function. Here’s simple Program to generate Fibonacci Series using Recursion in C++ Programming Language.

## What are Functions ?

Function is a block of statements that performs some operations. All C++ programs have at least one function – function called “main()”. This function is entry-point of your program.

A function declaration tells the compiler about a function’s name, return type, and parameters. A function definition provides the actual body of the function.

## Defining a Function : :

The general form of a C++ function definition is as follows:

return_type Function_Name( list of parameters )
{
//function’s body
}

• return_type : suggests what the function will return. It can be void, int, char, some pointer or even a class object.
• Function_Name : is the name of the function, using the function name it is called.
• Parameters : are variables to hold values of arguments passed while function is called. A function may or may not contain parameter list.
• Function body : is he part where the code statements are written.

Below is the source code for C++ Program for Fibonacci Series using Recursive function which is successfully compiled and run on Windows System to produce desired output as shown below :

### SOURCE CODE : :

```/* C++ Program for Fibonacci Series using Recursive function  */

#include<iostream>
using namespace std;

int fibonacci(int n)
{
if((n==1)||(n==0))
{
return(n);
}
else
{
return(fibonacci(n-1)+fibonacci(n-2));
}
}

int main()
{
int n,i=0;
cout<<"\nHow many terms for Fibonacci Series :: ";
cin>>n;
cout<<"\nFibonacci Series for [ "<<n<<" ] Terms as follows :: \n\n";

while(i<n)
{
cout<<"  "<<fibonacci(i);
i++;
}
cout<<"\n";

return 0;
}```

### OUTPUT : :

```/* C++ Program for Fibonacci Series using Recursive function  */

How many terms for Fibonacci Series :: 10

Fibonacci Series for [ 10 ] Terms as follows ::

0  1  1  2  3  5  8  13  21  34

Process returned 0```

Above is the source code for C++ Program for Fibonacci Series using Recursive function which is successfully compiled and run on Windows System.The Output of the program is shown above .
