OOP Lab 13: Mentorship System (Aggregation vs Composition)

Model an Academic Mentorship System using pointers as data members inside the Teacher class:

• ◦
  Attributes: studentID (int), name (std::string), cgpa (double).
• ◦
  Const member functions: getStudentName() const, getStudentID() const, getCGPA() const.
• ◦
  Method display() const: Prints student roll number, name, and CGPA.

• ◦
  Attributes: teacherID (int), name (std::string), department (std::string), Student* students[5] (array of pointers), int numStudents.
• ◦
  Constructor initializing teacher attributes and setting numStudents = 0.
• ◦
  Method assignStudents(Student* s[], int n): Populates internal pointer array with n student addresses.
• ◦
  Method displayMentorship() const: Displays teacher info and all assigned students.

• ◦
  Students exist independently; deleting/scope-exiting a Teacher does not destroy the Student objects.

• ◦
  Create student objects.
• ◦
  Create teacher objects and associate student pointer arrays.
• ◦
  Display mentorship assignments.
