How to access a nested classes data members if it is a pointer in the outer class

Ardaos (12)
Hello, everyone. I am very much still a noob programer and was seeking some help with how to access a nested classes data members if the outer class holds a pointer to the nested class.

I have two classes, Job and JobException. if Job receives input that is invalid for costOfJob it creates a JobException and throws it.

The first catch block in the Main function at the bottom of my code is where the problem is. I am not sure of the syntax to access the JobException.*Job.DataMembers or if it is possible.

also when I intialize JobEcxeption, which requires a Job pointer, I use JobException errorJob(this). Is this the correct way to send a pointer of the class you are in to another class?

I'm not opposed to a work around or redoing it if my code is inefficient. Pointers aren't my strong suit. Any and all feedback is appreciated. Thanks for your time.

wow, thanks! It was so simple. You saved me a lot of headache trying to figure this one out.
