Question

CS211 -- Lab 3 This lab is very similar the Ex03 of the “Class" lecture I placed in the web. Make sure to study that example before you do this lab. You should make up a transaction file with at least 3 records of students. Write a main program that creates a collection of students. Your transaction file contains a set of information about studehts. Your program should contain four classes: StudentProfile, Person, Student, and Course StudentCollection has the following attributes vector-StudentProfile> StudentProfile class has the following attributes Person Student StdInfo Person class has the following attributes long string string int char SSN Fname Lname Age Gender ('M' for Male and 'F' for Female) Student class has the following attributes long Course Course Course Course Course StNo Coursel Course2 Course3 Course4 Course5 Course class has the following attributes long string urseN
