Desision tree c4.5 algorithm built in C++

Details

This program creates a decision tree using the C4.5 algorithm.

Output:

Data set after binary split (change numerical attributes into nominal ones)

The decision tree in the form

<Attribute1>
	value1: class {counter1 counter2 total}
	value2:
		<Attribute2>
			(...)

Tested in:

g++ version 11.2.0

linux distro :arch linux x86_64

kernel : 5.16.15-arch1-1

compiling:

g++ -o driver driver.cpp

runing:

./driver file1.csv file2.csv

Note:

it is advised to run with "./driver file1.csv file2.csv | less" , this will make it so you can start at the top and let you freely move trough the output.

Another option is piping the output to a file with "./driver file1.csv file2.csv > tree ", it achives the same result.
