To implement an algorithm and understand its intricacies
Problem/Exercise
For this lab, you will complete two independent programs. For the first, you will implement functions which calculate the n^{th}^{}Fibonacci number. You must write two functions: one which simply uses recursion, and one which makes use of dynamic programming/memoization. Run
both programs with the provided lab07.cppfile and submit a written report which includes your pseudocode, the runtimes for each, and a briefdiscussion of the difference in runtimes.
The second assignment is to perform numerical integration. For this assignment, there will not be any user interface or reading in. You will be given a vector of ordered pairs (coefficient, power), and two doubles for upper and lower bounds of integration. From this information you must construct a polynomial function and numerically integrate it between the bounds given using the Midpoint Rule. Your program should iteratively improve its estimate until the difference between iterates is less than 0.0001.
For both parts of this assignment, you are allowed to use any C++ STL data structures. Your
final code will be in two files, memoization.h and integration.h. Both files must compile without errors using the provided Makefile. In order to thoroughly test your program, you will also
submit two input files named lab07_memo.txtand lab07_int.txt which have test cases for each program respectively.
Additional Requirements

Your memoization.h and integration.hfiles must compile and run with unmodified
versions of the provided lab07.txtand Makefile to produce the same output as our examples. If your class does not, then you’ll need to fix it. After you get your class working, you should create several examples on your own to further test your program to make sure it works with any valid set of test cases.

As a hint, you should run your fibonacci program on a range of values (e.g. 5, 10, 30, 100) to see how the runtime changes between memoized and normal recursive versions.

For numerical integration, use the midpoint rule with initial step size = 1. At each step reduce the step size by half (1 to ½, ¼, etc.)

Stop when the difference between the current and previous iteration is less than 0.0001.
Examples
Your C++ source code should be in a file called memoization.h and integration.h, and it should
be compiled into an executable called lab07.outusing our provided Makefile. The output of memoization.h and integration.hmust look exactly like the examples below when run on the command line on our Unix machines.
./lab07.out
x^2+1 0 1

x^4x^3+x^21 3 4

x^0.5 0 .5

Source Code Requirements

Put a comment at the top of your source code file with your name (first and last), the date of your submission, your lab section, and the assignment’s name.

All functions should be commented. Use inline documentation as needed to explain ambiguous, tricky, or important parts of your code.

All source code must follow good programming style standards such as properly indenting source code; and all variables, functions, and classes should be wellnamed.

Your class must use dynamic memory allocation and deallocation properly, which means your class cannot contain a memory leak. You may use valgrind to check for memory leaks. Refer to the Unix manual and valgrind’s online documentation for more information on valgrind.

Your integration program must take input in the form of ordered pairs. The first number is the coefficient, the second is the exponent.
Submission
Before the date/time stated on the CPSC 2121 Canvas webpage, you need to submit your code to handin under the correct lab assignment. Make sure to submit all of the following.

All source files required for this lab (memoization.h and integration.h)

Your testing file (lab07_memo.txtand lab07_int.txt)
After you submit, always double check that the file(s) you submitted were the correct version. To double check, download the submitted file(s), put them on one of our Unix machines, and make sure they compile and run correctly.
Grading
If your class does not compile on our Unix machines or your assignment was not submitted on time, you will receive a grade of 0 on this assignment. Otherwise, your class will be graded using the criteria below.
Your class works correctly with our testing program(s)
Proper variable names, documentation, and code organization
Your class uses dynamic memory allocation/deallocation
6 points
2 points
1 point
properly (no memory leaks)
Alternate testing file containing map and query data you
1 point
created for testing which is distinct from that provided.
You must test, test, and retest your code to make sure it compiles and runs correctly and efficiently on our Unix machines with any given set of valid inputs. This means that you need to
create many examples on your own (that are different from the provided lab07_memo.txtand lab07_int.txt) to ensure you have a correctly working class. We will only test your program with valid sets of inputs.
