Lab Assignment 12-Using C++

This lab is based on your lab assignment 10, the difference is that you are required to read from text files and write to text files, there are two text files, read.txt and write.txt, the code should read RUID and NAME from read.txt. After that user will choose as many options they like, write the options and results to wirte.txt, in the attachment, there is a sample read and write txt file.

The name and RUID is read from read.txt, if it find a string RUID in read.txt, you need to create a new Linkedlist to store the following RUID and name(there are multiple RUID in the string), finish reading all the elements in read.txt, use operator overloading + to connect linkedlists together. After that when user choose a option, the corresponding option and result will be written to write.txt

Reminder: make sure the text your code write to write.txt is the same as the example in write.txt

Also the sorting function is to sort by RUID also RUID is just a four digit-ID number.

Here is the example I/O in terminal

The combine list is as follow: (This comment is not part of the code what combine list means is creating 3 list objects list 1, list 2 and list 3. Then adding list1 and list 2 to equal list 3, so list1+list2=list3, this is the reasoning for overloading the + operator.)
