The brackets are fine. Add "return 0;" at the end of the main.

But I agree that this is not your problem, just a good coding standard to use.

They are very simple to use, use #ifndef filename_h and #define filename_h before any code, and then #endif at the very end of the file. It helps to protect against repeated inclusions.

You need only to include the header file and then create an instance of that class. If your class is called Foo, you would do:

Foo myClass;

myClass.(all the members should now be present) =...
