You are to include the following particulars in your submission: Course Code, Title of the ECA, SUSS PI No., Your Name, and SubmissionLate submission will be subjected to the marks deduction scheme. Please refer to the Student Handbook for details.MPORTANT NOTE ECA Submission Deadline: Sunday, 12 May 2019, 2355 hoursECA Submission GuidelinesPlease follow the submission instructions stated below:This ECA carries 70% of the course marks and is a compulsory component. It is to be done individually and not collaboratively with other students.Object Oriented Programming代写SubmissionYou are to submit the ECA assignment in exactly the same manner as your tutor-marked assignments (TMA), i.e. using Canvas. Submission in any other manner like hardcopy or any other means will not be accepted.Electronic transmission is not immediate. It is possible that the network traffic may be particularly heavy on the cut-off date and connections to the system cannot be guaranteed. Hence, you are advised to submit your assignment the day before the cut-off date in order to make sure that the submission is accepted and in good time.Once you have submitted your ECA assignment, the status is displayed on the computer screen. You will only receive a successful assignment submission message if you had applied for the e-mail notification option.Object Oriented Programming代写ECA Marks Deduction SchemeObject Oriented Programming代写Please note the following:a)Submission Cut-off Time – The cut-off time for ECA submission will be at 2355 hrs on the day of the deadline. All submission timings will be based on the time recorded by Canvas.b)Start Time for Deduction – Students are given a grace period of 12hours. Hence calculation of late submissions of ECAs will begin at 12:00 noon the following day (this applies even if it is a holiday or weekend) after the deadline.c)How the Scheme Works – From 12:00 noon the following day after the deadline, 10 marks will be deductedfor each 24-hour  Submissions that are subject to more than 50 marks deduction will be assigned zero mark. For examples on how the scheme works, please refer to Section 5.2 Para 1.7.3 of the Student Handbook.d)Any extra files, missing appendices or corrections received after the cut-off date will also not be considered in the grading of your ECA assignment.Plagiarism and CollusionObject Oriented Programming代写Plagiarism and collusion are forms of cheating and are not acceptable in any form of a student’s work, including this ECA assignment. You can avoid plagiarism by giving appropriate references when you use some other people’s ideas, words or pictures (including diagrams). Refer to the American Psychological Association (APA) Manual if you need reminding about quoting and referencing. You can avoid collusion by ensuring that your submission is based on your own individual effort.The electronic submission of your ECA assignment will be screened through a plagiarism detecting software. For more information about plagiarism and cheating, you should refer to the Student Handbook. SUSS takes a tough stance against plagiarism and collusion. Serious cases will normally result in the student being referred to SUSS’s Student Disciplinary Group. For other cases, significant marking penalties or expulsion from the course will be imposed.Note to Students:Submit your solution document in the form of a single MS Word file. You are to include the following particulars in your submission: Course Code, Title of the ECA, SUSS PI No., Your Name, and Submission Date. Put this information in the first page of your solution document. Use the template word document provided SUSS_PI-No_FullName_ECA.docx. Rename the file with your suss PI and full name join with “_ECA” e.g. “SUSS_PI- TomTanKinMeng_ECA.docx” (without the quotes). Do NOT submit as a pdf document.You should make only one submission for ECA.You are to copy and paste the source codes of each program you write into your solution document, provided in the template word document. If you submit the source codes as a screenshot, you will be penalized. Submit screenshots for only the output of your program, where applicable.Object Oriented Programming代写Answer all questions.
