#include <iostream>
#include <fstream>
#include <string>

using std::cout;
using std::endl;

int main()
{
	std::ifstream ifs("d:\\data.txt");
	std::ofstream ofs("d:\\data.bak");
	std::string text = "";

	for (int i = 0; ifs.eof() != true; i++) 
		text += ifs.get();

	text.erase(text.end() - 1);     

	ifs.close();

	ofs << text;
	ofs.close();

	return 0;
