File output problem using ofstream

Hi, this code doesn't seem to output the file properly. Can you help? Thanks.

Code:

#include <iostream.h>
#include <stdio.h>
#include <fstream.h>
#include <stdlib.h>
#include <string.h>

int main()
{
	// hours for each day
	double mon;
	double tue;
	double wed;
	double thu;
	double fri;
	double sat;
	double sun;

	double totalhours = 0;
	double totalpayed = 0;
	double payrate = 6.27;

	char filename[256];
	char totalpayed_str[256];

	cout << "Enter the hours worked on the following days:\n\n";
	
	cout << "MONDAY: ";
	cin >> mon;
	cout << "\nTUESDAY: ";
	cin >> tue;
	cout << "\nWEDNESDAY: ";
	cin >> wed;
	cout << "\nTHURDAY: ";
	cin >> thu;
	cout << "\nFRIDAY: ";
	cin >> fri;
	cout << "\nSATURDAY: ";
	cin >> sat;
	cout << "\nSUNDAY: ";
	cin >> sun;
	cout << "\n";
	cout << "******************************************************\n";

	totalhours = (mon + tue + wed + thu + fri + sat); // sun not added
	totalpayed = payrate * totalhours;
	totalpayed += ( sun * (payrate * 1.5) ); // time and a half on sundays
	totalhours += sun; // add sun into the total hours becuase it was missed

	cout << "You will be payed $" << totalpayed << " for working " << totalhours << " hours this week.\n";

	// print out file ----------------
	
	_gcvt(totalpayed, 5, totalpayed_str);
	strcpy(filename, "C:\\");
	strcpy(filename, "Getting paid ");
	strcpy(filename, totalpayed_str);
	strcpy(filename, " this week.txt"); 
	
	ofstream outfile(filename);

	outfile << " ";

	outfile.close();

	return 0;
}

What do you want in the file?

b.t.w. _gcvt is not ANSI C/C++ (use sprintf instead)

Code:

ofstream outfile;
outfile.open ("test.txt", ofstream::out | ofstream::app);
if(outfile.is_open())
{
   outfile << "You will be payed $" << totalpayed << " for working " << totalhours << " hours this week.\n";
   outfile.close();
}
