Software Operation

I have this code, it seems to be in c++. It came across my desk off a communication system and I want to make sure it is not anything important in operations.

I was hoping to run it, but i don't even know where to begin.

At this point I am trying to figure out what it is doing at each step, process, etc.

I am an electrical engineer in Canada but with no software background what so ever. Anyone can help. Even running it would be assume. Not sure where to start, go :(

I will show the code below,

Question 1: It open a file --> c:\\test.txt <-- is this something every operating system has in its hard drive, a test txt file?

Question 2: What is it doing? I am lost, thank you for any assistance in advance

#include "stdafx.h"

#include <fstream>

#include <iostream>

using namespace std;

class flipflop{

bool Q, data_in, feedback_active, aux_in;

public:

flipfop(int output, int fb){Q=(output>0)?true:false;feedback_active=(fb>0)?true:false;);

flipflop(){Q=false;feedback_Active=false};

void input(int d, int ad){data_in=(d>0)?true:false;aux_in=(ad>0)?true:false;};

int output(){return Q?1:0;};

void evaulate(){Q=(!feedback_Active)?data_in:(data_in^aux_in);};

};

int _tmain(int argc, _TCHAR* argv[])

{

int mask,i,d;

ifstream in_file;

char one_byte;

in_file.open("c://test.txt,ios::binary);

flipflop Z0(0,1);

flipflop Z1(0,1);

flipflop Z2;

while(in_file.read(&one_byte,(int)1)){

for(i=7;i>=0;i--){

mask=0x01<<i;

d=((unsigned int)one_byte&mask)?1:0;

Z0.input(d,Z2.output());

Z1.input(Z0.output(),Z2.output());

Z2.input(Z1.output(),Z2.output());

Z0.evaluate();

Z1.evaluate();

Z2.evaluate();

}

}

cout<<"FINAL RESULT\n";

cout<<"\t"<<"\t"<<Z0.output() <<" " << Z1.output() << " " << Z2.output() << "\n";

return 0;

}
