Hi please im having problems with programming

its meant to be an app but i dont know how to go about it without having errors

this is the problem

2) in this exercise you are going to update a very simplified version of a COVID contact tracing app using arrays of structs. The struct should contain at least the name of the user and an array of integers containing the places where the user has been (assume that each place is allocated a different number. Your program should have the menu: 1) introduce new user 2) introduce site visit (each time a user goes to a particular place). This is the simplified equivalent of scanning a QR code when you enter a shop. 3) check which users have been in a particular place (this would be used if an outbreak was detected in a place and users needed to be contacted) You might want to include more information in the struct (e.g. an unique number)
