ok, Thanks, I forgot to instantiate the class.
: Suppose you have a project with a class that computes the average of 10 numbers. In a different file you already written a class "Add_numbers" that adds up numbers. What you can do here, and is, in my opinion, the logical thing to do, is to incorporate the class
: "Add_numbers" into your project. Go to File->Add Existing Item and select the project that contains
: the class you want. Then select the class itself.
: This class in added in full to your project. Now you can access any method of this class by calling "Add_numbers.method_name". Voila.(do not forget to
: make an object of this class first).
