You can declare the object as a global varaible and then use it from both files.  One file must declare and define the object.   like

SomeClass ObjectName;

Then any other file that wishes to also use the object needs to declare the object as an external, like

extern SomeClass ObjectName;

Then that file can then use the object.   If there are many files that need to use the object, you could place the external declaration in an .h file and include it into all the files.  (you could even include it into the file that has the object's definition, it won't cause a problem.)

Let me know if you have any questions.
