CSC270 C Programming Test CORRECTIONS

Professor Pepper

DUE DATE: 10/28/2015 at 2:25 pm

Name: _________________________ Date: ________________

Directions:

· You must turn in a completed extra credit, not partial.

· You are permitted to discuss this exam with other students currently enrolled in this course.

· You are encouraged to use notes and textbooks (including from this class). If you use a reference, other than our textbook, for a particular problem, then it must be noted at the end of the problem.

· Do not submit any work that you do not fully understand. The professor reserves the right to ask any student to explain any portion of this correction assignment.

· If you decide to take on this assignment, you must report for 1 hour of tutoring within the Department of Mathematics and Computer Science, Bridges or the Learning Center.

· You may discuss these problems with the tutors; however, a tutor cannot do these problems for you!

· To be eligible for 60% of the points you lost on the C Programming Test:

· For each of the 2 construction questions:

o Copy your original answer into notepad++. Use comments before at least half the lines to explain exactly what every line of the code you submitted was creating. In comments, Write a few sentences about how it did not match the specification and what should be done to change the program.

o Write a working program by making as few changes as possible. It must keep your variable names and be an outgrowth of your original structure. This must be your own work. Tutors can show you how to execute similar logic, but cannot answer this question.

o Hand me: the 2 commented exercises and the corrected code - 4 files altogether

· For the multiple choice questions: - creation of a study guide

o Find the problem concepts: look through the incorrect answers, and write a list of facts or concepts you had difficulty with.

o Read about those concepts and facts  in your textbook and talk to your friends about it.

o Then, take your problem concepts page to a tutor (learning center, math department tutor, professor, or bridges program tutor only) to learn and write a study guide containing an explanation and an example for each fact or concept on your list.

o Have the tutor sign your study guide to verify that you worked on this guide with the tutor.   

o Hand me: one study guide covering all topics that gave you trouble in the multiple choice section SIGNED by the tutor

· Write a quick reflection on how you plan to approach learning C++

§ 1 paragraph reflection paper on the methods you employed to learn C programming before the Midterm. Also, describe new approaches you plan to implement in the next portion of this course.

§ Hand me: one paragraph with full sentences reflecting thoughtful contemplation of study methods

· You must abide by Adelphi’s honor code – “every student is on his or her honor not to cheat, nor to plagiarize, nor to act dishonorably” – will be strictly enforced; any violation will result in an immediate failure and possible disciplinary actions for all parties involved.

Some more details on the study guide:

Here is an example: 

Note, if there could be a textbook chapter title with their topic, it is too broad. Find topics by combing through all their test answers to figure out what facts and concepts tripped you up. It should be broader than - the answer to this question is.. but not book chapter broad. You may see an overarching topic that you can include as well.

Here are some good topics: 

• When should I use the * and when do I not use the * with pointers  
• When do I use & and * when passing variables to  scanf
• When working with arrays, what is the difference between pointers and array variables?
• How do I pass back more than one value from a function without using an array?
• How do I send arrays back and forth between a main function and another function? 

Here is an example explanation with examples under a topic on the study guide: For the study guide for "When should I use the * and when do I not use the * with pointers", something like this would be fine:

When should I use the * and when do I not use the * with pointers

Creating a pointer is different from using a pointer for the *. 

Place the * between the type and the variable name for creating a pointer.

· int * y

· int* function (int * x)

Place the * before the variable name when you want the value being pointed at when using the pointer after creation. 

· *y = 7;

When don't I need a * when creating a pointer: Never (However an array is very much like a pointer with no *, but let's deal with that in another topic altogether.) 

And when don't I need a * when using my pointer variable:

· When I want to change the address the pointer looks at: 

o y = &v

o y = myarrayvariable

o y = someOtherPointerToAnInt

o y=y+1 (pointer math)

· When I want to use the pointer to get to an array element

o y[2] = 7

o int b = y[3]

These can be picayune topics, so feel free to comb your books, or my study guide ( http://home.adelphi.edu/~pe16132/csc270/ppt/summaries/C%20Programming%20Test%20Summary.htm

or other study guides on my presentation site http://home.adelphi.edu/~pe16132/csc270/ppt.html

or any other sources on the internet for good answers. This does not have to be completed in one session. You only have to work with a tutor for one hour on this, but are welcome to work more or to complete it on your own. I do want the study guide, as far as it has progressed, signed by the tutor as proof of working with the tutor, but it does not have to be completed when you see the tutor.
