I just want to ask if this is correct? I believe I wrote back to the data file correctly, but I have never done a project like this and I want to be sure I didn't mess it up. Also, would I write the registration data back the same way as I did with the member data? Where would I include the class types that are listed? The code I have currently and the data files are below, thank you so much!

Add code to the exit_program method. In this method you will: Add the code to write the member data back to the data file member.txt. Add the code to write the registration data back to the data file register.txt. You will have to change the call to the exit_program method, passing the arrays and counts
