I am getting complier errors from the code I posted a screenshot at the bottom can you help identify the problem

Source code for main.cpp:

#include #include "roster.h" using namespace std;

int main() {

int numStudents = 5;

const string studentData[5] = { "A1,John,Smith,John1989@gm ail.com,20,30,35,40,SECURITY", "A2,Suzan,Erickson,Erickson_1990@mailcom,19,50,30,40,NETWORK", "A3,Jack,Napoli,The_lawyer99yahoo.com,19,20,40,33,SOFTWARE", "A4,Erin,Black,Erin.black@comcast.net,22,50,58,40,SECURITY", "A5,Sam,Burns,sbur117@wgu.edu,29,10,20,30,SOFTWARE", };

Roster* ros = new Roster(numStudents); for (int i = 0; i parseThenAdd(studentData[i]); }

cout printAll(); cout

ros->printInvalidEmails(); cout printAverageDaysInCourse(ros->getStudent(i)->getStudentID()); } cout
