Thread: classes and outputting to a file

hey I am trying to write a program that converts decimal to hex, binary etc. I then need to take the info and output to a file. I am using a class and have the couts in my class functions I was wondering if there was a way I could write to the file from the class functions.

Code:

#include <iostream>
#include <iomanip>
#include <iostream>
#include <fstream>
using namespace std;

void binary(int num);
void hex(int num);
void bcd(int num);
int remove();

class converter
{
    private:
    #define MAXSIZE 12
    int bin[MAXSIZE];
    int sec[4];
    int remainder;
    int newValue;
    int k;

    public:
    converter();
    void binary(int num);
    void hex(int num);
    void bcd(int num);
    int remove();


};

converter::converter()
{
    remainder = 0;
    newValue = 0;
    k = 0;
}


void converter::binary(int num)//converts to binary from decimal
{
     ofstream myfile;
     newValue = num;

   while(newValue >= 1)
    {
        remainder = newValue%2;

       if (remainder == 0)
        {
            bin[k] = 0;
            k++;
        }


        else
        {
            bin[k]= 1;
            k++;
        }
        newValue = newValue/2;
    }


    for(k; k<8; k++)
    {
        bin[k]=0;
    }

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

        myfile << bin[k] << endl;
    }

}

void converter::hex(int num)
{
    ofstream myfile;
    k = 0;
    int temp = 0;
    newValue = num;

  while(newValue >= 1 )
    {
        remainder = newValue%16;

            bin[k] = remainder;//used to add the remainder into the array
            k++;


        newValue = newValue/16;

    }
     for(k; k < 8; k++)//fills up the array to follow the format
        {
            bin[k] = 0;
        }

    for(int g = 1; g>=0; g--)
    {
        temp = bin[g];
        cout << setw (40);

        if(temp <= 9)//converts to the appropriate letter for hexadecimal.
        {

            myfile << temp;
        }
        else if(temp == 10)
        {
                myfile << "A";
        }
        else if (temp == 11)
        {
               myfile << "B";
        }
        else if (temp == 12)
        {
               myfile << "C";

        }
        else
        {
