1 PCS1-Ch-4C-Functions-3-HW.docx CSCI 1320 Initials P a g e 1 If this lab is an Individual assignment, you must do all coded programs on your own. You may ask others for help on the language syntax, but you must organize and present your own logical solution to the problem. No lab is complete until the student submits the signed pledge form associated with that lab. I realize that no coded programs will be graded until I turn in the sign & pledge form associated with that program; any late penalties will continue to compound until the pledge form is submitted. If this lab is a team assignment, both team members may share logic as they program side by side on their own computers. Each person must type all of his/her own code as part of the learning process. Team assignments are never to be You do this portion and I ll do that portion or You do this lab and I ll do the next lab. Some of the lab assignments will have short answer questions. These short answer questions will be spot checked and graded for completion, but not checked for accuracy. Once these labs are graded and returned, I encourage you to compare answers with another class member who has also had the lab graded and returned. I/We realize that the penalty for turning in work that is not my own, or assisting others in doing so, can range from an "F" in the class to dismissal from Trinity University. I realize that it is a violation of academic integrity to share any portion of this lab with any students (outside my 1320 team)! Print Name Time Required =. Hrs.

Practice with Tuples and answer the short answer questions before attempting to write the code for this lab. 2] Get a copy of the code. TomH-HW-4C-Functions-3-Student.scala rename the file TomH-4C.scala use your first name & Initial. 3] Set the diagnosticlevel to 1. Write the code for isinteger refer to slides. Test it. When all works well, continue. 4] Set the diagnosticlevel to 2. Write the code for getint refer to slides. Test it. When all works well, continue. 5] Set the diagnosticlevel to 3. Write the code for quadratic. I have written all of the test code for diagnostic levels 3 and 4. Test your function. <12 Points> 6] Your job is to develop the test functions for diagnosticlevels 5-12 in accordance with the documentation requirements. What To Turn In No Lab Is Complete Until Both Are Complete ] You sign & submit the Pledge form. a) Make sure that all program files have a header box with a purpose that clearly defines what you are accomplishing in this lab.

6 PCS1-Ch-4C-Functions-3-HW.docx CSCI 1320 Initials P a g e 6 b) Make sure that each and every program function has a well formed documentation box that clearly describes the purpose. c) Make sure that each and every program function header box has the appropriate Written By and Date. d) Review the Pledge statement e) Sign & Pledge f) Record the amount of time you think you spent on this lab g) Staple all pages of this lab. Fold in half length-wise (like a hot-dog). Put your name on the outside. Place it on the professor desk before the beginning of lecture on the day it is due. The penalty for late homework will not exceed 25% off per day. 2] Place all programming code associated with this program, if any, in the Professor s Code Drop Box a) I do not accept programs by mail; do not submit labs via ! Comments A] Programs that do not compile are worth little, if anything. B] If a print statement format is off, the penalties will often be less than the 25% per day late penalty; turn in the lab. You would not be happy if you went to Best Buy and purchased a large screen TV that did everything except show the picture; you would consider it pretty worthless. Most users consider software that does not work properly pretty useless as well. If the lab is not working correctly, credit will be small (if any); you might be better to accept a 25% (1 day) late penalty and turn in the lab working correctly! C] Start all programs early so that you can get in contact with the professor if you have problems. D] If you are turning in this lab late, you may hand it to me if I am in the office put it in the mail box outside my office door slide it under the outer door to our suite {if locked} E] Backup your programs in at least three places. Put a copy on your Y drive. Put a copy on your flash drive. Put a copy on your personal computer. Send yourself a copy in your .
