struct courseType
{
   string name;
   string code;
   int noOfStudents;
   studentType *studentList;
};

int main()
{
   courseType theCourse;
  
   theCourse.name = "Intro to Programming";
   theCourse.code = "BCS 120";  
   cout << "Enter the number of students in the class: ";
   cin >> theCourse.noOfStudents;

Explanation / Answer

#include<iostream>
#include<cstdlib>

using namespace std;

struct studentType
{
string name;
int ID;
};

struct courseType
{
string name;
string code;
int noOfStudents;
studentType *studentList;
};

int main()
{
courseType theCourse;
  
theCourse.name = "Intro to Programming";
theCourse.code = "BCS 120";
cout << "Enter the number of students in the class: ";
cin >> theCourse.noOfStudents;

   // Q a.
theCourse.studentList = new studentType[theCourse.noOfStudents];

//Q b
for(int i=0; i<theCourse.noOfStudents; i++){
       cout<<"Enter name of "<<(i+1)<<" student: ";
       cin>>theCourse.studentList[i].name;
       cout<<"Enter ID of "<<(i+1)<<" student: ";
       cin>>theCourse.studentList[i].ID;
   }

   //Q c
   for(int i=0; i<theCourse.noOfStudents; i++){
       cout<<"Name: "<<theCourse.studentList[i].name<<", ID: "<<theCourse.studentList[i].ID<<endl;
   }
  
   // Q d
   delete[] theCourse.studentList;

system("pause");
return 0;
}
