Create new instance of class c

I'm happy to help! However, I need more information to create a new instance of a class C. Can you please provide the following details:

1. What programming language are you using?
2. What is the definition of class C? (i.e., what are its properties and methods?)
3. Do you want to create a new instance of C using a specific constructor or method?

Once I have this information, I can assist you in creating a new instance of class C.
