Question

Q6. Write a function (not a method of a class) void student Tester) which contains code to test the classes you have developed in the previous three questions. When this function is called it should: Create two research students .Create two taught students, and register them for three modules each .Make an array of pointers to Student and point the elements of the array at your four student objects. Run a for loop which calls each student's printinto0 method, using the array of pointers.

Here is the code from the previous three steps:

#include <iostream>
using namespace std;

class Student
{
private:
//class variables
int ID;
string firstName,lastName;
public:
Student(int ID,string firstName,string lastName) //constructor
{
this->ID=ID;
this->firstName=firstName;
this->lastName=lastName;
}
int getID() //getter method
{
return ID;
}
virtual string getType() = 0; //pure virtual function
virtual void printInfo() //virtual function to print basic details of a student
{
cout << "Student type: " << getType() << endl;
cout << "Student ID: " << ID << endl;
cout << "Student name: " << firstName << " " << lastName << endl;
}
};
class ResearchStudent : public Student //class ResearchStudent inherits class Student
{
private:
//class variables
string supervisor,thesis;
public:
//constructor
ResearchStudent(int ID,string firstName,string lastName,string supervisor,string thesis): Student(ID,firstName,lastName)
{
this->supervisor=supervisor;
this->thesis=thesis;
}
void printInfo() //method to print the additional details of a student
{
Student::printInfo();
cout << "Supervisor name: " << supervisor << endl;
cout << "Thesis name: " << thesis << endl;
}
string getType() //method to get student type
{
return "Research Student";
}
};
class TaughtStudent : public Student //class taughtStudent inherits class Student
{
private:
string modules[10];
int numRegisteredModules;
public:
TaughtStudent(int ID,string firstName,string lastName): Student(ID,firstName,lastName) //constructor
{
numRegisteredModules=0;
}
void printInfo() //method to print the additional details of a student
{
Student::printInfo();
cout << "Modules: " << endl;
for(int i=0;i<numRegisteredModules;i++)
cout << modules[i] << endl;
}
bool registerFor(const string &moduleName) //function to add an additional module
{
if(numRegisteredModules==10)
return false;
modules[numRegisteredModules]=moduleName;
numRegisteredModules++;
return true;
}
string getType() //method to get student type
{
return "Taught Student";
}
};

int main() //main method to test the functions
{
ResearchStudent r(101,"Debjit","Ganguli","Debayan Ganguly","AI");
r.printInfo();
TaughtStudent t(102,"Indrajit","Ghosh");
t.registerFor("AI");
t.registerFor("ML");
t.printInfo();
return 0;
}

Note: Could you plz go this code and let me know if u need any changes in this.Thank You
