Struggling to complete this program
I am having some trouble finishing this exercise here. I am supposed to have this program run normally, then ask for an employee ID or name, and then store the data under that name in a txt file, and then loop the program. I have the entire program finished, just stuck on having to put in that loop and have the txt file store the data under the user input name/number. How do I solve this? (the code is very long, I will add it in a comment.)
