Improved PP3.zip available

This is the same problem that cropped up in the PP2.zip - I copied the wrong .zip file to make the PP3.zip. Sorry. If you notice any other problems, let me know.

PP3 is now available

Topics for second exam

PP2: STL list class problem & workaround

It seems that there may be a bug in the STL list class. Fortunately, there seems to be an easy workaround.

The symptom is:

  "/opt/SUNWspro/WS6U2/include/CC/Cstd/./list.cc", line 351:
    Error: Too many arguments in call to 
    "std::list>::__adjacent_merge(
         std::list>::iterator,
         std::list>::iterator,
         std::list>::iterator)".
  "/opt/SUNWspro/WS6U2/include/CC/Cstd/./list", line 465:
     Where: While instantiating 
     "std::list>::sort(bool(*)(const int&,const int&))".
  "/opt/SUNWspro/WS6U2/include/CC/Cstd/./list", line 465:
     Where: Instantiated from non-template code.

    CC = CC -template=wholeclass,extdef

    CC = CC -template=extdef

Note about PP2 makefile capability

Improved PP2.zip available

• The visitors provided in the Visitor directory have been generalized so you can use them directly in your code, without having to write new ones.
• The LRSList.cc file had an incorrect method return type for its find method. This does not affect any code you might write, but is potentially confusing.
• The Container.h file was missing an #include. This did not result in a compilation problem in the sample code because other files included the required file, but could potentially have resulted in failed compiles for your code.

Bug fix for GUI code

student> from tcmdwin.cpp:
student>         case Key_add:
student>           {
student>                 cout<<"add pressed";
student>                 break;
student>           }
student>         case Key_sub:
student>           {
student>                 cout<<"subtract pressed";
student>                 break;

student> How can I fix this?

me> Thanks for catching this - it's my mistake.
me> 
me> If you go to line 110 of tcmdwin.cpp, you will see a line that looks

me> 
me> {C_Button,Key_sub,Key_add,"+",NoList,CA_Size,isSens,frm1,Key_equal,Key_sub,20,"plus"},
me> 
me> The second item in this structure, "Key_sub", should be "Key_add".

I have also fixed this in the ReviewProject.zip file in /projects/CSE250, so if you download a fresh copy this change will be there. It is probably easier, if you have already modified this code with your own contribution, to just edit line 110 as noted above.
