OOP Lab 08: Student Records, Static Metrics & Object Pointers

LIVE← Prev Next →

Problem Objective

Create a Student class for university cohort tracking:

Private Data Members:

◦
studentID (int): Unique roll number.
◦
name (std::string): Student name.
◦
department (std::string): Academic department (e.g. "CS", "SE", "EE").
◦
CGPA (double): Cumulative grade point average.
◦
static int totalStudents: Tracks total instantiated student records.

Constructors & Methods:

◦
Constructor with default arguments: Student(int id = 0, std::string name = "Unknown", std::string dept = "General", double cgpa = 0.0) incrementing totalStudents.
◦
Static function: static int getTotalStudents().
◦
Constant member functions: getCGPA() const, getDepartment() const, getName() const, getStudentID() const.
◦
display() const: Prints formatted record.

In `main()`:

◦
Instantiate an array of Student objects.
◦
Display total cohort count via static function.
◦
Filter and display students belonging to a specified department using an object pointer Student* ptr.

Expected Terminal OutputStandard Out

Total Registered Students: 4

[*] All Student Records (Iterating with Pointer):
ID:  101 | Name: Ali Khan     | Dept: CS    | CGPA: 3.85
ID:  102 | Name: Sara Ahmed   | Dept: SE    | CGPA: 3.92
ID:  103 | Name: Bilal Tariq  | Dept: CS    | CGPA: 3.45
ID:  104 | Name: Zainab Noor  | Dept: EE    | CGPA: 3.70

[*] Department Filter: [CS]
ID:  101 | Name: Ali Khan     | Dept: CS    | CGPA: 3.85
ID:  103 | Name: Bilal Tariq  | Dept: CS    | CGPA: 3.45

[✓] Student records & pointer traversal verified (Time: 0.008s, Memory: 2.1 MB)

Execution Constraints

›Constructor must provide default arguments for all parameters
›static totalStudents tracking object instances
›Use object pointer (Student* ptr) for array iteration and selection
›Const member functions for getters

Implementation Checklist

Define Student class with private fields and static totalStudentsImplement constructor with default argumentsImplement const getters and display() methodImplement static getTotalStudents()In main(), create array of Student objectsUse Student* pointer to filter and display students by department
