Please don't put "using namespace" inside header files. This can cause
conflict with code that includes the header but doesn't expect to get
the namespace.

In Ruby, variables do not have types (all variables are references to
Objects, and the type of the Object is determined dynamicaly). If you
write instead:
a=10
b=20
Example.sum(a,b)
I think it should work.
Note that you don't need to terminate your lines with a semicolon in
Ruby.
