Hi Guys,




I was practising with the following code but had a problem during compilation. The compiler says;

"error: unreported exception IOException; must be caught or declared to be thrown".

Please what could be the problem here?

You can also "duck" the exception if you would like by declaring that the main function throws IOException like this:

I recommend to try also VC.demo() to get a deeper understanding of polymorphism
