![**Question 3: Fibonacci Sequence Function**
Write a user-defined function called `Fibonacci` that calculates the Fibonacci Sequence. The sequence is defined as follows:
\[ F_n = F_{n-1} + F_{n-2} \]
Where:
- \( F_0 = 0 \)
- \( F_1 = 1 \)
The user-defined function will take one argument of type `int` that will represent \( n \) in the sequence and return the result of the sequence to the main function to be displayed. Inside the main function, prompt the user for input for the value of \( n \) greater than or equal to 2. If the user doesn’t enter a valid input, the function should not be called, and an error message should be displayed.
*Hint: Use a `for` loop.*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F778ebef2-39f8-4792-902a-c383666adfe6%2Fe3583600-6f6b-4ccc-94d0-905886d4f2f6%2F5hk6hyd_processed.jpeg&w=3840&q=75)

Expert Solution

Step 1
#include <stdio.h>
//Fibonacci Series using Recursion
int fib(int n)
{
if (n <= 1)
return n;
return fib(n-1) + fib(n-2);
}
int main ()
{
int n ;
// take input from user
printf("Enter the number");
scanf("%d",&n);
printf("%d\n", n);
printf("%d", fib(n));
getchar();
return 0;
}
