Preferably, given your code, after a end of line (carriage return) is entered.

not working dude...

I think it's because you're using a char to store the result of getchar(). getchar() returns an int. EOF is -1, which can't be represented by a char.

Try changing ch to int.

I'm pretty sure CTRL-Z is the right key sequence -- do it a few times then hit enter and it should die.

thanks everyone now its working....it was not working because of getch() function it was needed two enter for exit...

Code:

#include <stdio.h>

main()
{
    int ch;   //char to int
    FILE *ptr;
    ptr = fopen( "test.txt" , "w" );
    printf( "enter data for file\n" );
    while((ch=getchar())!=EOF)
    {
        fputc(ch,ptr);
    }
    fclose(ptr);
}
