"Best" is a value judgement which only you can make.

But in principle there is nothing wrong with classes whose purpose
is just to perform certain tasks.

Usually you define the class in a .h file and implement its member
functions in a .cpp file which includes the .h file.

So file "xyz.h" would contain

class XYZ
{
public
int doTask( int x );
};

and "xyz.cpp" would contain

#include "xyz.h"

int XYX::doTask( int x )
{

//.......................
}

The place where doTask() is called from also needs to include
xyz.h.
