**Fibonacci Series using Recursive function**

**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 ?*

*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 : :**

**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 : :**

**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 : :**

**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 .

**Thanks for reading the post….**

Thanks for this post. it helps me in my assignment. Can you please tell me this code is right if i want to use for loop?

Yes this post or code is right using for loop. You may go through that.
