MTRX3760 C++ Mechatronic Systems Design

MTRX3760 - Lab 1

Introduction to OOD in C++

This assignment contributes 5% towards your final mark. It is to be completed individually, not in groups.

Total Marks: 100.

This assignment is due before the start of your next lab session, i.e. before the start of the Week 2

lab session for Thurs/Fri labs, and before the start of the Week 3 lab session for Monday labs . Late

assignments will be subjected to the University’s late submission policy unless accompanied by a valid special consideration form. Plagiarism will be dealt with in accordance with the University of Sydney plagiarism policy. Lab submissions will not be accepted more than a week after the due date.

Assignments will be assessed based on the following components. Incomplete submissions will have

severely reduced marks:

● Report : Submit a .pdf report using the class Canvas site. The report can be very simple, and needs only directly address the questions laid out in the assignment.

The cover page for your report should include your SID and tutorial section, but do not include your name to comply with the University’s anonymous marking policy.

Code appendix : The appendix of your report must contain a printout (in text format) of all source code written for the assignment. File header comments and proper formatting will be critical to making this section readable.

Code : Submit your code (code only, no binaries) in a .zip file via the canvas site.

You may find libreoffice writer or google or microsoft’s online tools useful for preparing your report. For printing out and appending code to your report, you can use:find . -name "*.cpp" -o -name "*.h" | xargs enscript --color=1 -C -Ecpp

-fCourier8 -o - | ps2pdf - code.pdf pdfunite <report name >.pdf code.pdf < concatenated report name >.pdf

The first command recursively finds .cpp and .h files and formats them as a pdf called code.pdf . The second command concatenates the code to an existing pdf file.

You have been provided with an object-oriented implementation of a combinatorial logic simulator. Read the provided A1.LogicSim.v0.cpp including the details laid out in the header comment. Compile, run,

and understand this implementation.

Understanding the Provided Code

The code provided has some important limitations, but it works. Without changing the code’s structure or behaviour, answer the following briefly in your report:

[5 marks] Draw the logic circuit that the provided code simulates. Include labels for the wires and gates.

[5 marks] Write down the sequence of class interactions that occurs when the first call of DriveLevel occurs in main . This should be a bulleted list in which each bullet corresponds to an interaction between functions or classes.

An example class interaction sequence from a different project:

● main calls CKitchen.OvenIsHot

● CKitchen.OvenIsHot calls mRobot.GetThePizza, passing it an OvenID

● … more function calls

● CRobot.GetThePizza returns program flow to CKitchen.OvenIsHot

● CKitchen.OvenIsHot returns program flow to main

Hints:

● You may wish to instrument the code without changing its structure or behaviour by adding console output (std::cout) throughout.
