I need help with the following questions, any assistance is greatly appreciated. I have added the code that I have figured out so far, and the files that accompany it. Thank you so much!

Add code to the Modify member method. In this method, you will increment the member count (mcount) and prompt the user for new member data to be read into the member parallel arrays. You will have to change the call to the modify_member method, passing the arrays and the member count

Add code to the Modify Registration method In this method, you will increment the registration count (rcount) and prompt the user for new registration data to be read into the registration parallel arrays. You will have to change the call to the modify_registration method, passing the arrays ant the registration count The possible class names are: Yoga Karate AerobicsI AerobicsII SwimmingI SwimmingII

The current code:
