Regarding the new save/load facility, should it replace the existing save/load implementation ? | |
| No. The new save/load format should come in addition to the existing format. |
Some of the features are actually already implemented in my submission for assignment 4a. Does it count? | |
| Yes, but you should explicitly mention these features in the list of features (in the "Help->About" dialog box) so I would not miss them. |
The textual file format you presented does not conform with my implementation, so i need to change it. Am I allowed to do so? (The problems: I have an unique Id for each object, the price we use is a double, The passanger type is a String...) | |
|
No, you are not allowed to change the format. I am sure you can find a creative solution for the problems you mention. |
Can we assume that in the textual file we open, the rows are sorted so that passengers and flights come first and only then the tickets? | |
| No, you cannot assume that. |
Should the buttons in the toolbar show icons, or can they show text instead? | |
|
They can show text. But such toolbars make the program a little less user-friendly (compared to tool-bars with icons), so you may loose points in the "usability" grade. |
Should the toolbar contain all the actions available in the menus, or should it contain only the frequently used ones (such as add/remove rows, undo/redo, check data)? | |
| As in most GUI applications, the tool-bar should offers only the frequently used actions. |
What happens if a passenger has two (or more) flights from an airport to two different destinations? How do we compute the "remaining" value in such circumstances? | |
|
The remaining value should contain the maximum length of a sequence computed over all possible sequences leaving the target airport. For example, if we have these tickets (assuming all departures take place less than X hours from the previous arrival): Ticket 1: Tel-aviv -> NY Ticket 2: NY -> Chicago Ticket 3: NY -> Toronto Ticket 4: Toronto -> Moscow Then we have that: remaining(Ticket 1) = 2 remaining(Ticket 2) = 0 remaining(Ticket 3) = 1 remaining(Ticket 4) = 0 |
You said that the features in the excercise are worth 50 points overall. There are 10 features, are we to understand that each feature is worth 5 points? | |
| The features have different weights based on their difficulty. On average each feature is 5 points. |
When calculating the remaining value my algorithm goes into an infinite loop if a flight duration is zero. Can we avoid that? | |
| In such cases you may display a special symbol (such as: "???") indicating that you could not compue this value |
What file-name suffix should the program use for the textual format? | |
|
Use the ".csv" suffix |
