Hi,
I have a total of 5 files:

1. test.cpp
#include"TextTranslator.h"
#include<fstream>

int main()
{
ifstream examplefile("readme.txt");
TextTranslator tt(examplefile);
tt.translation(examplefile);
return(0);
}

2. TextTranslator.cpp
#include"TextTranslator.h"
#include<iostream>
#include<fstream>
#include<stdlib>
TextTranslator :: TextTranslator(){
}
TextTranslator :: TextTranslator(ifstream examplefile){

if (! examplefile.is_open())
{
cout << "Error opening file";
exit (1);
}
}
void TextTranslator :: translation(ifstream examplefile)
{
ofstream outfile("readme.xml");
outfile << "<Document>\n";
outfile << examplefile.rdbuf();
outfile << "\n</Document>";
outfile.close();
}

3. TextTranslator.h
#include"Translator.h>
#include<fstream.h>
class TextTranslator: public Translator {
public:
TextTranslator();

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.

And trying to post 3 times in the wrong forum is clearly against the rules. Please do not do it again.
