DecisionTree_C4.5 program about decisiontree_c4.5 HOT 5 OPEN

Thank you very much for the follow up. I really appreciate your concerns. Please read below what are the changes I have done to compile this program under Visual Studio 2013.

Errors:
-------
Error 12 error C2057: expected constant expression
Error 13 error C2466: cannot allocate an array of constant size 0

Modification:
--------------
I did the following modification to compile it successfully.
//int Count[Unique_Values.size()] = {0}; (change it)
vector < int > Count(Unique_Values.size());

Errors:
--------
Error 17 error C2057: expected constant expression
Error 18 error C2466: cannot allocate an array of constant size 0

Modification:
--------------
I did the following modification to compile it successfully.
//int Count[Score_Range.size()] = {0};
vector< int > Count(Score_Range.size());

After the above mentioned modifications when I compiled the program in Visual Studio 2013 there was the following error.

Error 37 error C4700: uninitialized local variable 'Tree' used
Error 38 error LNK1257: code generation failed
Tree = Tree->BuildTree(Tree, Matrix); //Error 37

I did the following modifications to compile it successfully.
//TreeCls * Tree; (change it)
TreeCls * Tree = NULL;

Though the program was compiled successfully. But I do not how the executable file build from the program would provide results of C4.5 on the input line (can see in the main() function) MatrixCls Matrix("C:\Golf.dat");

Can you please check the changes that I have done. Also how I can get the output results in viewing the situation that I am working on visual studio 2013.

OK, I will find some windows machine and compile this for you, I don't have any experience with VS, compile this source code should be trivial in a Linux machine. Just read your email this night, I will response in this week. 😃

Sorry, I still cannot get a windows pc with vs, you can compile it in Linux terminal with command
g++ -std=c++11 DecisionTree_C4.5.cpp
and then there should be an a.out executable file, you can run it with typing ./a.out in the terminal

Hi zgyao,

I have implemented your code and got it executing, but with the golf example it only shows the outcome as "Play", "Don't Play". How can I see the associated confidence factor for each outcome ?

Thanks !
