Hello world! I'm talking about how to create a Zip file in Windows.
I have a directory called mycpp,
and I want to ZIP a particular program in here,
The one I want to zip is called source.cpp,
which would be the source code for a C++ program.
If I right click on that and pick WinZip,
I can say "Add to Zip file" and a window comes up and I can give it a name.
For this particular file the name I want to give it is
a last name and first name and underscore and the name of the project and Moss.zip.

That's fine, and after I do that I can click add or I can just press enter,
and it tells me that my file has been created.
and you can see the original size was quite a bit bigger than the compressed size.
and if we just scroll over and you can see
the size of the zip file is 3 KB (kilobytes),  and the CPP file is 6 KB,
so that's one of the reasons for zipping a file.
If you're going to submit it you can make it quite a bit smaller 
so that it doesn't take as long to upload.
