Description

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 continuation of assignment 0 but now written in the C++ language. It works the same. It is a console application that holds the data of an animation application (there is no actual animation graphics in the assignment) using a forward list (aka singly-linked list) of unspecified length in dynamic memory for its data.
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 and Frame class member functions and not add any new ones. Everything you write is in the files Animation.cpp and Frame.cpp.

The Animation is a series of Frames held in a forward list. When the list runs it displays the details of each Frame at intervals of 1 second using the system clock. You can:
• Add a new Frame to the Animation at a position selected by the user
• Delete all the Frames in the Animation
• Run the Animation to show the list of Frame details one after another at 1 second intervals
• 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) and at any instant there is never any unused dynamic memory – only allocate what you need
• input and output is done with cin and cout
• you can only use functions like strlen() and strcpy() or similar etc. from the standard library to handle strings of null terminated chars (names can be up to 256 chars long)
• 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 (such as running an empty list etc.),
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 zip file (not RAR) containing only
Animation.cpp and Frame.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 tyleraAss1CST8219.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.
