I can't make sense of it either The extension '.htm' suggests that you should be able to open it in Internet Explorer but trying this, just produces 'This Page cannot be displayed.'
Looking at the text, if it is loaded into a text editor, reveals a typical source program, ready for compiling into a Target program (Object code)which would then run correctly.
Perhaps the Source file has been mistakenly posted, instead of the Object file.
