Student Roster

A C++ console application that manages a student class roster — parsing enrollment data, validating records, and reporting statistics by student and degree program.

Built as the capstone project for C867: Scripting and Programming – Applications at Western Governors University.

---

Overview

The application ingests a fixed set of student records, parses them from comma-delimited strings into structured objects, and produces several reports:

• Full class roster
• Invalid email addresses (missing @, missing ., or containing spaces)
• Average days to course completion per student
• Students filtered by degree program
• Dynamic add and remove operations with verification

Classes

Student

Represents a single enrolled student.

Member	Type	Description
studentID	std::string	Unique identifier (e.g. A1)
fname / lname	std::string	First and last name
email	std::string	Email address
age	int	Student age
numDays	std::array<int, 3>	Days to complete each of 3 courses
degree	Degree	Enrolled degree program

Full getter/setter interface, a parameterized constructor, a parse-friendly default constructor, and a print() method for formatted output.

Roster

Manages a dynamic array of Student pointers.

Method	Description
add(...)	Adds a student by individual fields
add(Student)	Adds a pre-constructed Student object
parse(string)	Parses a comma-delimited data string into a Student
remove(studentID)	Removes a student by ID and shifts the array; reports if not found
printAll()	Prints every student in the roster
printInvalidEmails()	Flags emails missing @, missing ., or containing spaces
printAverageDaysInCourse(studentID)	Prints the average completion days for one student
printByDegreeProgram(Degree)	Filters and prints students by degree

Degree (enum)

enum Degree {
    SECURITY,
    NETWORK,
    SOFTWARE
};

Building and Running

Requirements

• Windows with Visual Studio 2019+ (Community edition is free)
• C++14 or later (configured in project properties)

Steps

1. Clone or download the repository
2. Open StudentRoster.sln in Visual Studio
3. Press Ctrl+F5 to build and run without the debugger

Command Line (MSVC)

cl /EHsc /std:c++14 main.cpp student.cpp roster.cpp /Fe:StudentRoster.exe
StudentRoster.exe

---

Key Concepts Demonstrated

• Object-oriented design — encapsulated Student and Roster classes with clean public interfaces
• Dynamic memory management — heap-allocated student array using new / delete
• CSV parsing — std::istringstream + std::getline to tokenize delimited strings
• String validation — email format checking without external libraries
• Pointer arithmetic — manual array compaction on removal
• Enum types — Degree enum for type-safe degree program representation
• Separation of concerns — declarations in .h, implementation in .cpp

---

Known Limitations

• Roster capacity is initialized to 5; the resize path in add() is present but not fully functional — extending beyond the initial capacity is not supported in the current version.
• SIZE and COUNT are implemented as global variables; a future refactor would make these private members of Roster.
• No destructor is implemented on Roster — the heap-allocated student pointers are not explicitly freed on program exit.
