1 National Taipei University of Technology 0. Introduction Object-Oriented Programming (Fall, 2008) Homework # 1 (Due: Mon., Oct. 6, 24:00) In order to improve your programming skill, we will assign you a non-trivial C++ program. The program will cover some of the important C++ language features, design patterns, unit testing, and GUI development, and it consists of six parts. Project Management Tool (PMT) is a program designed to help a project manager (PM) to monitor the progress of their project. There are many kinds of views in the PMT, and those prove difference viewpoints to help PM to understand project state. The most important views are Gantt chart view and Resource view. The Gantt chart view (see Figure 1) helps PM to monitor whether the project is on schedule. If it is not, it helps PM to pinpoint the remedial action needed to put it back on schedule. The Resource view (see Figure 2) is another view, which helps PM to plan resources to ensure that these resources arrive or are available when the tasks are due to begin and that there are no delays waiting for the resources. Figure 1 Gantt view

2 Figure 2 Resource Usage View 1. Homework#1 In the first homework, your program needs to load the PMT file correctly (the file format of PMT file is listed in section 2), and prints some information about the file. After the program is launched, the program asks user to type the file name and shows the prompt menu. User can select menu operations to execute corresponding functionality. There are 6 options in the prompt menu. The first option is to list all the resources on the screen. The second option is to list all the tasks. The third option is to determine the duration time for each task. The duration time is a value that specifies the days to run the task (Duration = estimatedend estimatedstart). Beses, the duration calculation needs to skip non-working days. For example: if task 1 has attributes estimatedstart: 2008/09/19 and estimatedend : 2008/09/23, then the duration is 3 days. The fourth option is to list all task dependencies. The start date of dependent task (child task) must be after the end date of the parent task. The fifth option is to list all task resources. The last option is to exit the program. 2. PMT file format The PMT file is dialect of XML. All PMT files must conform to the XML 1.0 specification, as published on the World We Web Consortium (W3C) website. An example of the PMT file is listed in Figure 3. At the top level, a PMT document is a <project> element, and the <project> element consists of a <Resource> (required element) and a <Tasks> (required element) sub-element. The detail of the elements will discussed in sections 2.1 and 2.2.

5 name estimatedstart estimatedend state Unique task entifier Task name Estimated start date of this task Estimated end date of this task The status of task <Taskgroup> (optional) -- The <Taskgroup> element can contain the following: <Task> and <TaskGroup> element. <TaskDef> (optional) -- The element is the optional element of <Task> and <TaskGroup>. It defines the dependent tasks. Id The dependent task <Resourceref> (optional) The resource has been used in the Task or TaskGroup. Unique resource entifier be assigned 3. Grading After completing the homework#1, your program should prove the following features: 1. List all the resources on the screen. (30%) 2. List all the tasks and task groups on the screen. (25%) 3. List Task Duration (10%) (You can use the computedayduration function in the skeleton to help you to complete this feature). 4. List Task Dependency (10%) 5. List Task Resource (10%) 6. Write the document (5%) Please write a C/C++ program to perform these features described above. The

6 efficiency of your program is not a concern in this homework. The grading of this homework will be base only on the following criteria: (a). Compile and run the program without errors. (b). Read inputs in exactly the described format. (c). Good coding style (the criteria will be listed on Table 1). (10%) (d). Please don't modify the function interface (add parameter, del parameter, or change the function name) in the skeleton. If you change the interface, you will get zero score. Table 1 Bad coding style Abbrev. Bad Coding Style A Inadequate commenting B Names (entifiers) are not meaningful C Use of unnamed constant D Indentation does not indicate program structure 4. Homework submission The homework needs to be submitted in both ways: 1. Electronic version All the related files in this homework have to compress in one ZIP file. The ZIP should include the following items: (1). Source code (the entire eclipse project). (2). Report (PDF or WORD). Please login the Open Cyber Classroom using your student ID from the following URL: You have to upload the electronic version to the web. 2. Printed version You have to write a brief summary for this homework that should include the following items: (1). The features that you finished in this homework. (2). Snapshots of program execution. (3). The implementation class diagram. (4). Source Code Listing as appendix. (5). Measure the time that you spent in this homework. Please record the time precisely in the following table (Table 2).
