Assignment 4 Student Record Manage Program With File Stream

In Assignment 3, write a program to perform student record manage for class IST311. It contains two parts: student record class and main program. It should get the student information from the user and set up student record class array with proper size. The program will perform sorting student record by last name then first name, compute final grade, set up ranking by final grade, and then print out the student ranking list information. Modify Assignment 3 program to read the student’s information from the file “students.txt”, then processing students’ information, which are same as assignment 3.

In addition, the program needs to write the students information with grade list into the file “studentGrade.txt”, then ranking the student by final grade and write to the file “gradeRanking.txt”. The program should ask the user to choose the method of input student’s information, which are from keyboard or from file. If the user chose input from file, the program needs to ask the user for file name; the program need to validate the file. Keep the “readdata”, “sorting” and “searchHighestGrade” are same as Assignment 3 and add following functions to your Assignment 3:

  • Write “readFiledata” function that is the implementation of reading the data from the user input file and store into student record array.
  • Write “rankingSort” function that is the implementation of ranking student record by student’s final grade without moving data and set rank variable to rank number.
  • Write “displayRank” function that is the implementation of writing the student grade ranking list to output file “gradeRanking.txt” and to screen. It only displays student’s number of ranks, last name, first name, final grade.
  • Write “display” function that is the implementation of writing the student record from student record array by using student class displayAllGrade() function to output file “studentRecord.txt” and to screen.

Paper For Above Instructions

The objective of this project is to develop a program for managing student records for class IST311, which includes two main components: a student record class and a main program. The program will allow for student information input either through keyboard entry or from a file. The program will then manage this data through various functions, including sorting and ranking students based on their final grades, and outputting the results to files.

1. Requirements Overview

The program must be able to read student information from a file named "students.txt," process this information, and then output data into various files that include student grades and rankings. The user will be prompted to choose their input method, and if they opt for file input, the program must verify the file's existence and validity. Among the core functionalities, sorting by last name and first name will be a significant aspect of managing student records.

2. Implementation Details

The program will employ several essential functions to fulfill the outlined requirements:

2.1. Function: readFiledata

This function will handle reading student records from "students.txt." The data will be stored in an array of student records. Each record entry will consist of student names and associated grades, formatted correctly for processing.

2.2. Function: rankingSort

Ranking students will involve sorting their final grades without rearranging the actual data in the student record array. This will maintain the integrity of the original data while allowing for the correct ranking to be displayed.

2.3. Function: displayRank

This function will display and write student rankings to the file "gradeRanking.txt." The output will include the number of ranks, last name, first name, and final grade of each student. This information will help instructors and students understand the performance metrics clearly.

2.4. Function: display

The display function's purpose will be to output student records into "studentRecord.txt". The student class will implement a function to display the complete grade records for each student, providing a comprehensive view of performance throughout the course.

3. File Format for Input

The input file format needs to adhere to a specific structure for successful parsing. The first line should indicate the number of records, followed by lines containing details for each student. For example:

4. User Interaction

The program will prompt the user to enter their preferred method of data input. If choosing to read from a file, explicit instructions will guide the user to provide the correct filename, while the program will check for the file's validity. This interaction enhances user experience, allowing flexibility in input methods, which is essential for program adaptability.

5. Conclusion

This assignment thus encapsulates an essential programming exercise that emphasizes data handling, file I/O concepts, and structured programming practices. Not only will the students learn to manage data efficiently, but they will also enhance their problem-solving capabilities within a real-world context. Completing this assignment will prepare students for the complexities of data management systems often encountered in professional environments.
