    Exclamation 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

    PHP Code:

    //Program written by Akilla //

    #include <stdio.h>
    #include <iostream.h>
    #include <conio.h>

    int leapyear(int year)
    {
        if ( (
    year%4==0) && (year%400==0) )
        {
            return 
    1;
        }

        if ( (
    year%4==0) && (year%100!=0) )
        {
            return 
    1;
        }
        
        return 
    0;
    }

    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.
    LB0: * Life once school is done
    LB1: N <- WakeUp;
    LB2: N <- C++_Code;
    LB3: N >= Tired : N <- Sleep;
    LB4: JMP*-3;

    binary mode is that


    #include <fstream>
    using namespace std;

    int main()
    {
    fstream File("test.txt",ios:ut,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)
