Description

Operators

NOTE: Plan to finish a few days early to avoid last minute hardware/software holdups for which no allowance is given.

Purpose: This is a development of assignment 1 with the addition of a two ready-made container class templates and overloaded operators. It works in a very similar way. It is a console application that holds the Frames of an Animation application (there is no actual animation graphics in the assignment) using a forward_list class template of unspecified length in dynamic memory. The forward_list is a container class that supports fast insertion and removal of elements and is implemented as a singlylinked list just as you have used in assignments 0 and 1.
In addition a Frame now has set of Display objects associated with it. You can think of them as the separate graphical components of a Frame that combine the make the complete image (– they might be green/blue-screen overlays as in chroma keying). A Display object holds the pixel location that it is to be overlayed in the frame and also the duration for which it should be displayed. The set of Display objects is held in a vector – another common container class template, more flexible but not (for some applications) as fast the forward list, which is designed to be minimal.
Part of the code is shown on the next page; it is also on Blackboard in a text file that you can copy and paste. You MUST use this code without modification (not a single character changed): no code added or removed, no new global variables or functions, no new classes, no macros, no defines and no statics. Your task is to implement, using C++, only the Animation, Frame and Display class member functions and the global insertion operators and not add any new ones. Everything you write and submit is in the files: Animation.cpp, Frame.cpp and Display.cpp.

The Animation is a series of Frames held in a forward_list. Each Frame holds its list of Display objects in a vector. A Display object contains its display time which is set by the user – therefore the fixed Frame display time of 1 second that was used in previous assignments is gone and is replaced by the individual Display times that the user specifies. You can:
• Add a new Frame to the Animation at a position in the forward list selected by the user • Delete all the Frames in the Animation
• Run the Animation to show the list of Display details of each Frame one after another at the display intervals specified by the user when the Display was entered – note that the output counts up the seconds
• concatenate two Frames to make a single Frame with combined Displays that is automatically added to the start of the forward_list
• Quit
An example of the output of the running application is given at the end. Yours must work identically and produce identical output.

Note the following:
• dynamic memory management is done with new and delete (not malloc, realloc or free)
• input and output is done with cin and cout
• there is no unused dynamic memory at any time
• string objects are used in the Animation and Frame classes to hold strings (a char array is still used in the Display class)
• Release of dynamically allocated memory is done in destructors so there is no resource leak (or you lose 30%).
See the Marking Sheet for how you can lose marks, but you will lose at least 60% if:
1. you change the supplied code in any way at all (not a single character) – no code added or removed, no macros, no defines, no statics and no additional classes, global functions or variables,
2. it fails to build in Visual Studio 2015,
3. It crashes in normal operation,
4. it doesn’t produce the example output.

Part of the code is shown on the next page. You MUST use this code without modification. Your task is to add the implementation of the class member functions.

What to Submit : Use Blackboard to submit this assignment as a plain zip file (not RAR or 7-Zip or 9 Zip) containing only Animation.cpp, Frame.cpp and Display.cpp. The name of the zipped folder must contain your name as a prefix so that I can identify it, for example using my name the file would be tyleraAss2CST8219.zip. It is also vital that you include the Cover Information (as specified in the Submission Standard) as a file header in your source file so the file can be identified as yours. Use comment lines in the file to include the header.

Before you submit the code,
• check that it builds and executes in Visual Studio 2015 as you expect – if it doesn’t build for me, for whatever reason, you get a deduction of at least 60%.
• make sure you have submitted the correct file – if I cannot build it because the file is wrong or missing from the zip, even if it’s an honest mistake, you get 0.

There is a late penalty of 25% per day. Don’t send me files as an email attachment – they will get 0.

Supplied code (also in a text file you can copy and paste on BlackBoard). Don’t change it.
