Wich IDE are you using?

I'm using Visual Studio

[Pontus]

Try using DevC++. It far more easy to use. Maybe that'll help.

[marol44]

I'm having an issue with the syntax and I also have an issue with undefined variables. Even if I use a different IDE I will still have the same issue.

[marol44]

OK I've made a change and now I'm down to 21 erors Can someone please take a look and let me know where I'm going wrong.
