File I/o

Dear Friends,

I have written the code below in an effort of laerning File I/O and port programming. I am coding using the VC++ 6.0 compiler. The code runs well. Pliz someone help me modify the code so that the program output is captured and saved to a file. The program is to prompt a user for a filename.

My code is:

Code:

---

/* program to read and write to and from the printer port.*/
/* the three port registers are used*/

#include <iostream>
#include <string>
#include <time.h>
#include <conio.h>

#define DATA        0x378  /*Data Register base address*/
#define STATUS  DATA+1 /* Status Register address*/
#define CONTROL  DATA+2  /*Control Register address*/


using namespace std;

int main()
{

//prepare for processing text
        bool MoreLinesToProcess=true;
       
                while (MoreLinesToProcess){
                //process next line
                bool MoreCharactersOnCurrentLine=true;

                cout<<"please type a line of text:"<<endl;

                while (MoreCharactersOnCurrentLine){

                /*process next character on current line*/
                        char s,n;  //CurrentCharacter;
                        if (cin.get(s)){
                /*process current character on current line*/
                                if(s=='\n')
                /*found newline character that ends line*/
                                        MoreCharactersOnCurrentLine=false;
                                else  {
                                       
_outp(CONTROL,_inp(CONTROL)&0xF0|0x04); /*initialise                                the CONTROL port for data input*/

_outp(DATA, s);  /*write c to the DATA register*/

        clock_t start_time;
                                        start_time=clock();
while ((clock()-start_time)<0.25*CLK_TCK);/*propagation                                        delay time*/

        n=(_inp(STATUS)&0xF0);  /* read MSnibble*/

        n=n|(_inp(CONTROL)&0x0F);/*Read LSnibble*/

                                        n=n^0x84; /*toggle bit 2 and 7 */STROBE pin is    hardware inverted.*/
                                       
                                       
        cout<<n;
        }
            }
        }

      }
      cout<<"I am doing fine";

return 0;
}

Code:

---

cout.sync_with_stdio(true); //Sync cout with the C io functions
freopen("file.txt", "w", stdout); //stdin for cin

---

Put that before you use cout.
You'll need <cstdio> (maybe <cstdlib>)
