We also introduced you to the basics of writing programming code, including writing to the standard output and accepting values at the keyboard. This led to a discussion of how you would temporarily store data in variables, arrays and structures and, since we tie the activities to the assessments, you practiced using these ideas while you worked with a compiler. Indeed, you might fall in love with programming and turn to it as a career as well! Part of the learning journey in computer programming is learning a way of thinking that may be foreign or new to you. Solving programs using computer programming requires you to think in a rather linear manner as you ‘empathise’ with the computer and what it needs in order to the job on your behalf. As you will learn in this module, there are other aspects that computing and information systems professionals need to be cognisant. Chief among them is considering how users of the computer program will be presented with information. How will they will interact with your software and how they will get what they need from it. You will undoubtedly recall a system you were required to use that was not ‘user-friendly.’ As you commence this second module, think about what that means, ‘user-friendly.’ Could you de�ne what it means if you needed to and you did not have access to an open Google search window? What is it about the software that makes it ‘friendly’? Is it that the software works with you, as a user? Is it that the software does exactly what you were expecting it to do? Is it that the user interface appeared to be intuitive and to was designed to be empathic toward your needs and wants out of it? While it is not entirely the scope of this 7/17/2019 Laureate International Universities https://laureate-au.blackboard.com/webapps/blackboard/content/listContent.jsp?course_id=_75722_1&content_id=_7771613_1&mode=reset 2/3 subject to be thinking about user friendliness, we introduce an important aspect of software design in this module; use cases, which are an industry standard method of communicating how the user will interact with systems. We will also continue your exposure to computer programming through C++. In this module we introduce further programming constructs that allow the programmer to have greater control over the �ow of the program. To do this e�ectively, you need to have a �rm grasp of the variables, arrays and structures that we introduced in module 1. We explore these in the second half of the module, as you consider using variables to control the �ow of the program. To �nish the module o�, we will also be introducing the notion of functions and recursion. These constructs are other options that allow the programmer to separate tasks that might be repeated and then write them only once; this is the main focus and bene�t of using functions. Recursion is a special type of function that calls itself, exiting when a predetermined condition has been met. Ready to get your hands dirty? Learning Outcomes Reading and studying this module and fully attempting all of the learning activities will help you to: identify the base use cases in a given scenario; identify included and extended use cases in a given scenario; draw and critique use case diagrams in small teams; test conditions using the ‘if’ and ‘switch’ statements in C++; use loops to iterate through code segments in C++; use functions to package code segments for re-use in C++; and appreciate recursive functions in C++. 7/17/2019 Laureate International Universities https://laureate-au.blackboard.com/webapps/blackboard/content/listContent.jsp?course_id=_75722_1&content_id=_7771613_1&mode=reset 3/3 In order to attain these learning outcomes, be sure to come to class (or attend webinars when scheduled) having read the module content— including the readings—and having made a solid attempt of the activities. It is essential that you do this as your classes are not designed to instruct, but to enrich your understanding of your self-directed learning through collaborative exercises, getting formative feedback and challenging your assumptions. You should come to class (or the webinars) fully prepared to contribute to the learning of others as well. You should discuss this approach with the learning facilitator if you’re unsure. Contents in the Module There are two parts to this module, 3.1 and 3.2. In the �rst part, we introduce basic aspects of software design concerning the user. This �rst taste of the uni�ed modelling language (UML) is followed up in subsequent subjects (i.e. Systems Analysis and Design) and for now we will focus only on a small subset of UML. In the second part, we resume our hands-on approach, introducing you to loops, conditions, functions and recursion. These constructs allow the programmer to control the �ow of the program and be able to handle errors in a graceful manner. If you are attempting this subject in a standard twelve-week trimester, each part of the module should take you one week. If you are taking the subject in a condensed or intensive mode, dedicate half a week to each part.

One technological change that suited its business structure and operations was the use of touch-screen terminals in its restaurants. The terminals allow customers to place their orders, including making customisations (e.g. extra cheese, no mayonnaise, etc.) and to pay for their order without needing to interact with a cashier. This, in turn, allows McDonald’s to put more staff into the area where meals are prepared in the hope of increasing the throughput of orders. The terminal is required to present the menu available to customers, allow them to place an order, customise their order. The terminal should then allow the customer to finalise and pay for their letter. It should finally print a receipt for the customer to take to the counter when collecting their meal. (This scenario is presented first because it is very similar to the worked example in this half of the module.) 07/09/2019 MODULE 3: SOFTWARE DESIGN AND CONTROL 2 Activities 2.1 Part A (needed for Assignment 2b – July 21) Prepare UML use case diagrams for the following scenarios, making assumptions where necessary: 2. PumpIt Power Gyms is a franchise chain of 24-hour gyms that operate across the country. Franchisees run and operate each of the gyms and the franchisor supports the ongoing operation through collective marketing, and standardised software. The system has access points at the front desk where members (the name given to customers when they have signed up to the gym) first enter and sign-in. The system then must allow a new customer to sign up to become a member, taking various personal information and issue them with a membership card that provides their authentication for entering the gym. It should request a monthly membership payment, that the customer makes. It should also assign the member a personal trainer and keep track of their progress through a plan of fitness prescribed by the trainer. If the member likes, they can sign up for classes such as Pilates and Yoga and also for fitness competitions. The gym will attract sponsors from the local area so that the winner of competitions will have a prize. 3. The local municipal library has a number of books in its collection, that borrowers can borrow for a predefined time. The library should allow new borrowers to sign up and then to borrow from that day. The library has determined that books should be returned within 8 weeks and if not, a late fine is to be applied to the borrower’s account. For each week the book is late, up to a maximum of the cost of the book’s replacement value, the fine is applied. Borrowers are required to pay their outstanding fines before they can borrow any other books. The library also provides access to specialised resources such as microfilm, newspapers, magazines and databases, all of which cannot be borrowed. The library runs a special program called story time, which is open to any borrower who has no outstanding fines to bring their children along on a Tuesday morning for somebody to read stories. 07/09/2019 MODULE 3: SOFTWARE DESIGN AND CONTROL 3
