>> i am able to get the output in command prompt... i need tat to be displayed on a text file...

Then the easiest solution is to re-direct the standard output to a file, by starting the program like this :

        ./program your_arguments > textfile.txt

The standard output will now no longer be written to the screen, but to the given textfile.txt.


You can obviously modify your code to write to a file rather than standard output. You'd have to use fopen and fclose to open and close a file resp. And you can replace all your printf calls with fprintf calls to write to the opened file.

What do you mean by "print the pixel" ? Weren't you talking about a text file ?

Can you show your code ?

You're using graphical output. How do you want to put that in a text file ?

What you probably want to do, is use an image manipulation library, like Cairo (http://cairographics.org/) or ImageMagick (http://www.imagemagick.org/script/index.php).

What do you mean ? A text file is for text data, not for graphical data.
