Oh, and I was still telling VS where my SFML files were so I could compile your project. Oh well.
Still, in all seriousness, debugging is an absolutely vital skill. You'll never finish a program longer than a few hundred lines if you don't learn how to use one. At the same time IDEs make it so easy that you should have no trouble learning it no matter what crappy tutorial you start with. In VS all you really do is make a debug build, click in the gray left-hand margin to set breakpoints on certain lines and when your program hits one, use the buttons in the debugging toolbar to do whatever you want from there. I'll let you figure out the rest from there (eg variable watching) since it's all pretty intuitive.
