9.If you pass n=2 to your function your 2nd term of Fibonacci series is 1 and (n-1)th= 1" term of Fibonacci series is 0 and (n+1)th= 3rd term of Fibonacci series is 1..
Transcribed Image Text:4. Write a function named 'sum_fib3' which will take input int n and return
the sum of the (n-1)th, nth and (n+1)th Fibonacci numbers. You can write additional functions
in your code if needed.
Description: The Fibonacci series starts with 0, 1, 1, 2, 3, 5, 8 and goes on. nth term of
Fibonacci series is summation of previous two terms.
Write the following Function:
int sum_fib3(int n)
{ int sum;
Your code goes here
return sum;
}
If you pass n=2 to your function your 2nd term of Fibonacci series is 1 and (n-1)th= 1st term of
Fibonacci series is 0 and (n+1)th= 3rd term of Fibonacci series is 1. So the function will return 1st
term+ 2nd term + 3rd term= 0+1+1=2
Sample cases:
when n=2 Sum_fib3(2)=2;
when n-3 Sum_fib3(3)= 4;
when n=5 Sum_fib3(5)= 10;
Write the function for this and also demonstrate the working of your function by calling it
in the main function.
