C++ Issue

I wanted to teach myself C++, and found myself a guide.

I have been using this one:
http://www.cplusplus.com/doc/tutorial/program_structure/

I'm on step one, took a full page of notes. I attempt compiling and running the initial given code with dev c++, but nothing. I have dissected it, and with the given info I can't figure out why it won't work. Any suggestions?

Why the fuck don't these idiots learn how to use the command prompt BEFORE they learn any programming AT ALL?
