Add this to your header or the top of your source file. You're welcome to split it into header/source.

#include <iostream>
#include <fstream>
#include <iomanip>
class logger 
{
public:
	logger(const char* filename)		// CTOR - Input is the filename that will be used for logging (good for debugging).
	{
		fout.open(filename);
	}
	~logger()				// Destructor flushes and closes the file.
	{
		fout << std::flush;
		fout.close();
	}
	
	template<class T>   
	logger& operator<<(const T& output)			// Accepts chars/strings/doubles/ints/etc.
	{
		std::cout << output;
		fout << output;
		return *this;
	}
	
	template<class Arg>	
	logger& operator<<(std::_Smanip<Arg> Smanip)	// Overloaded for parameterized manipulators (setw, setprecision, etc..)
	{
		(*Smanip._Pfun)(std::cout, Smanip._Manarg);
		(*Smanip._Pfun)(fout     , Smanip._Manarg);
		return *this;
	}
	
	template<class Arg>	
	logger& operator<<(std::_Fillobj<Arg> Fillobj)			// Overloaded for parameterized manipulator setfill()
	{
		std::cout.fill(Fillobj._Fill);
		fout.fill     (Fillobj._Fill);
		return *this;
	}
	
	logger& operator<<(std::ostream&  (*manip)(std::ostream &))	// Overloaded for Output manipulators
	{
		manip(std::cout);
		manip(fout);
		return *this;
	}
	
	logger& operator<<(std::ios_base& (*manip)(std::ios_base&))	// Overloaded for Basic format flags
	{
		manip(std::cout);
		manip(fout);
		return *this;
	}
private:
	std::ofstream fout;
};

Then implement it like this:

int main()
{
    logger log("output.txt");
 
    log << "Hello World" << std::endl;

    return 0;
}

Now just always use log instead of cout
