Writing to a TXT

ok guys.. I wrote a calendar program myself..
Now, I want to print the thing to a TXT file (it should give
an option Y/N)... when the answer is yes .. I
want it to print basically everything the program outputs
on the screen after the clrscr() command..

what's the easy way to do this..

here's my code

err... and please don't steal my code :-)

COOL PROGRAMS @ www.akilla.tk

You'll have to include fstream.h whenever you use files.

heres a simple program to do something like what you want..

Code:

---

#include<fstream.h>
int main()
{
char name[21],ans;
ofstream fout;

cout<<"ENTER NAME : ":
cin.getline(name,20,'\n');

cout<<"\n\nYOU ENTERED : "<<name<<"\n\n";

cout<<"DO YOU WANT TO WRITE THIS TO FILE [y/n] : ";
cin>>ans;

if(ans=='y' || ans=='Y')
{
 fout.open("MYFILE.TXT");
 fout<<"NAME : "<<name<<"\n";
 fout.close();

 cout<<"\n\nFINISHED WRITING\n";
}

return 0;
}

---

modify this to your needs.

I suggest: use the fstream, and use BINARY MODE... (if you are unfamilar with the fstream, as i believe u are, maybe you want to use text mode).

at that time format your output into the file with the variables you wish.

what's binary mode ? can you show me an example ?


www.akilla.tk

binary mode is that


#include <fstream>
using namespace std;

int main()
{
fstream File("test.txt",ios::out,ios::in,ios::binary);

char ch;
ch='m';

File.put(ch);

File.close();

exit(0);
}

I lost the code, please use the code option and put it in again..

also, what exactly is binary mode ?

is there a way i can printf it to the screen and to the file without
a whole lot of extra coding ? (please see my code above)

In your code you are mixing cout's and printf()'s.
One option is to use fprintf(). Just open the file using:

Code:

---

  FILE *fp;
  fp = fopen("calendar.txt","w");

---

Then change all cout's and printf()'s to fprintf()'s:
fprintf(fp,"January %d\n\n",year);

Or you could use the C++ style fstream.

And you would pass the file pointer to any functions which write to the file:

void drawcalendar(FILE *fp, int days, int firstday)
