1. Write an iterative C++ function that inputs a nonnegative integer n and returns
the nth Fibonacci number.
2. Write a recursive C++ function that inputs a nonnegative integer n and returns
the nth Fibonacci number.
3. Compare the number of operations and time taken to compute Fibonacci
numbers recursively versus that needed to compute them iteratively.
4. Use the above functions to write a C++ program for solving each of the following
computational problems.
I.
Find the exact value of f100, fs00, and f1o00, where fnis the nth Fibonacci
number. What are times taken to find out the exact values?
Find the smallest Fibonacci number greater than 1,000,000 and greater
than 1,000,000,000.
II.
I.
Find as many prime Fibonacci numbers as you can. It is unknown whether
there are infinitely many of these. Find out the times taken to find first 10,
20, 30, 40...up to 200 and draw a graph and see the pattern.
Report: Your report should address all of the below mentioned questions
1. Describe the Fibonacci series and write briefly what you have done in the
assignment.
2. What are the different skills, programming techniques have you used in order to
run the experiments?
3. What did you observe when you did the comparisons in Task 3 and Task 4?
Explain the graph that you have drawn from Task 4.1II?
4. List at least three different applications of the Fibonacci numbers to sciences and
describe one of them in details. Think of situation or a real world problem where
you can apply concept of Fibonacci numbers to solve it. Explain?
5. Write a paragraph, explaining what you have done in this assignment. What were
the challenges you have faced when solving these problems. How can you
improve the programs you have written to solve these problems?
