Project Description

The project is a simple file-based system for managing student records in C++. The system stores student records in a file using a variable-length record approach with a | delimiter. Each record is stored on a separate line with the fields separated by the | character in the following order:

Id|Name|Grade|Gpa|

where:

• Id is an integer representing the student's ID
• Name is a string representing the student's name
• Grade is an integer representing the student's grade
• Gpa is a float representing the student's grade point average.

The project provides several operations for managing student records, including adding a new record, updating an existing record, deleting a record, and searching for records by ID or name.

Student Information

The Student class contains the following fields:

• Id: An integer representing the student's ID.
• Name: A string representing the student's name.
• Grade: An integer representing the student's grade.
• Gpa: A float representing the student's grade point average.

Course Enrollments

Each enrollment record represents a student's enrollment in multiple courses. Each enrollment consists of the following fields:

StudentId|Course1|Grade1|Course2|Grade2|...|CourseN|GradeN|

• StudentId is an integer representing the student's ID.
• numCourses is an integer representing the student's enrolled courses count.
• Course1, Course2, ..., CourseN are strings representing the names of the courses.
• Grade1, Grade2, ..., GradeN are strings representing the grades achieved in each course.

The number of courses can vary for each enrollment.

Class Description

The VariableLengthRecord class provides methods for packing and unpacking records into binary format. The size of each record is determined by the length of each field and the | delimiter.

Overall, this project provides a simple and efficient file organization system for managing student records using a variable-length record approach.
