Assignment 4 Student Record Manage Program with File Stream Due Date: 4/30/2020 midnight. In this assignment, you will modify your previous student record management program to include additional functionalities involving file input/output operations. The program should allow users to input student information either manually from the keyboard or automatically from a specified file. After collecting the data, the program will process the student records by sorting them, computing final grades, ranking students by their grades, and outputting the results to specific files. Additionally, the program will include functions to read data from files, perform ranking sorting without moving data, and display the ranking list to both the console and files.

Assignment 4student Record Manage Program With File Streamdue Date 4

Student record management systems are essential tools for educational institutions to efficiently organize, analyze, and report student information. In this assignment, we will develop an enhanced student record management program that incorporates file input/output capabilities, advanced sorting, ranking, and comprehensive reporting features. The core of the program involves handling student data input, processing internal data structures, and producing analytical outputs in both textual and tabular formats.

Introduction

The management of student records has evolved considerably with advancements in programming and file handling techniques. A typical student record management system includes data input mechanisms, data storage structures, sorting algorithms, and output reporting. This project aims to demonstrate proficiency with file streams in C++, implementation of complex data operations, and creating user-friendly interfaces for data input and output. The program must satisfy functionalities such as flexible data input, error handling for file operations, sorting by multiple criteria, computing grades, and ranking students accordingly.

Design and Implementation

Data Structures

The backbone of this system is a Student class that encapsulates all necessary student information, including student ID, last name, first name, scores, final grade, and rank. An array or vector of Student objects will be used to store the data, with dynamic sizing based on user input or file content. Proper encapsulation and member functions are crucial for maintaining data integrity and modular code design.

Input Methods

The program prompts the user to choose between manual data entry or file input. If file input is selected, the system must prompt for the filename and validate the file’s existence and readability. The function readFileData will handle reading student information from the specified file, adhering to the predefined format. For manual input, the user enters data directly, which is then stored into the student array.

Data Processing

Once the data is inputted, the program performs sorting based on last name and first name to organize the records alphabetically. It then calculates each student’s final grade based on given scores, employing weighted averages or predefined criteria. Next, the program ranks students according to their final grades. The rankingSort function is implemented to sort students by final grade without moving data, instead updating a rank variable within each student object to preserve data integrity.

Output and Reporting

After processing, the program outputs a comprehensive student report, including all student details and grades, to the console and to the file studentRecord.txt. It also generates a ranking list sorted by final grades, written to gradeRanking.txt. The displayRank function manages displaying the ranking information, including rank, last name, first name, and final grade, in both the console and output files.

Additional Functionalities

• writeStudentGrades: Outputs each student’s information along with their final grade to studentGrade.txt.
• readFileData: Reads student data from a specified file, validating the input format and handling errors gracefully.
• rankingSort: Sorts student records by final grade while assigning rank variables without physically reordering the array.
• displayRank: Displays the ranked list to the screen and writes to gradeRanking.txt.
• display: Outputs the full student record list to the console and studentRecord.txt for review.

Challenges and Considerations

Implementing file handling robustly requires thorough validation checks for file existence, read/write permissions, and data format correctness. Sorting algorithms must be optimized for performance, especially for large datasets, to ensure efficiency. Maintaining data integrity when updating ranks without rearranging data demands careful design. Additionally, user experience considerations, such as clear prompts and error messages, enhance the program's usability.

Conclusion

This program demonstrates advanced file handling in C++, coupled with sorting, ranking, and reporting functionalities critical for effective student record management. The ability to read data from files, process it according to multiple criteria, and generate comprehensive reports prepares students for real-world data handling scenarios in educational administration. The project also emphasizes code modularity, error handling, and file validation, essential skills for software development in data-intensive domains.
