Writing An Image Within C++?
So here is what I am trying to do and am curious about. I have been doing the text tutorials on this site using filestream and what not to read and write .txt files i.e. text files automatically once the code is executed.
That's all well and fine and when you click the file it will create the a text file, but what about if you wanted to write binary data or data to a file and make it a a bitmap image?
Say I have an image on my computer ALREADY and I want to create an executable from c++ i.e. code, that when clicked on creates this IMAGE FILE instead of a standard text file that this site already shows you how to do.
Is this possible? If so how would such a thing be done? Thanks in advance

of course.
http://www.cplusplus.com/doc/tutorial/files/
see the part "Binary files" (if you haven't)
then
http://en.wikipedia.org/wiki/BMP_file_format#File_Structure
will explain what to write into a bmp. Other formats would be harder to do. I'm suggesting bmp because it doesn't have any compression.

In the same way that fstream makes it easy to use files, an image library simplifies image processing. So you'd not normally need to understand the details of image processing to do it.
