[Solved] SOLVED:Programming Project #2 SOLUTION

Assignment Overview This project focuses on some mathematical manipulation, in particular integer operations. It is worth 20 points (2% of your overall grade). It is due Monday, January 25th before midnight. The Problem (from the Handley Math Page, http://141.104.22.210/Div/Winchester/jhhs/math/puzzles/mtricks.html) Visitors, especially young ones, often waited for General Douglas MacArthur to perform a miracle, or at least utter something profound, when they met him. The General could not always live up to his press notices. So, MacArthur started using a mathematical trick that he described as the old number 115 as a way to maintain his image, have some fun, and mystify his guests. Ask your friend to write down the number of month in which he was born. (January is 1, February is 2, and so on). Turn your back so you cannot see what your friend is jotting down in response to your instructions. Then have that person write down: Month of birth (Example February): 2 Double it: 4 Add 5: 9 Multiply by 50: 450 Add friends age (Example 40): 490 Subtract 365: 125 At this point, ask your friend to call out the total, which in this case, is 125. In your head, quickly and secretly add 115. In this example, you will end up with 240. Then proclaim, Why, you were born in February and youre 40 years old. Heres how he did it. The first numberand the second if the total is a four-digit numberwill indicate your friends birth month, once youve added good old 115. The last two digits will indicate his age. Program Specifications Your program will play the MacArthur game as follows: 1. Print a message to the user about the game and explain the rules 2. Prompt the user for both a birth month (1 for Jan, 2 for Feb etc.) and their age. 3. Print out the special number that results from the algorithm above. 4. Add 115 to the number, and find the value of the last two digits (age) and the first one or two digits (birth month). 5. Print out the birth month and the age of the player Deliverables proj02.py your source code solution (remember to include your section, the date, project number and comments). 1. Please be sure to use the specified file name, i.e. proj02.py 2. Save a copy of your file in your CSE account disk space (H drive on CSE computers). 3. You will electronically submit a copy of the file using the handin program: http://www.cse.msu.edu/handin/webclient Assignment Notes: One of the main issues here is that we are working with integers, and division with integer numbers is a little different. Integer division always returns an integer result. Thus 10/3 yields 3. The operation 4/5 yields 0. There is another operator, called the modulus operator, which indicates the remainder after a division. The modulus operator is indicated by the % sign. Thus 10%3 is 1 (a remainder of 1). 4%5 is 4. You can use these facts to gather the digits in the hundreds, tens and ones place of a three digit integer. Try some experiments in the Python interpreter to see how to accomplish this task. To clarify the problem specifications, we provide at the end of this document a snapshot of interaction with the already written program. Getting Started 1. Using IDLE create a new program. 2. If you are in a CSE lab, select the H: drive as the location to store your file 3. Save the name of the project: proj02.py 4. Create the preface print information and prompt for the user integer 5. Run the program and fix any errors 6. Use the handin web site to hand in the program (incomplete as this point but you should continually hand things in) 7. Now, prompt for the two numbers and convert to integers (birth month and age). 8. Perform the calculations. 9. Separate the last two numbers from the sum (how to do that)? Print those numbers. 10. Now you enter a cycle of edit-run to incrementally develop your program. 11. Use handin to hand in your final version. Questions for you to consider (not hand in) 1. What happens when enter a non-number as a month or age? 2. What happens when you enter an integer age larger than 99? Sample Interaction
