By Abhiram eerla

This C++ code implements a student report management system with features to add, display, modify, and delete student records.

 

1. Class Definition (student):

   • Data members: name, roll, grade, and marks (Cpp, DAA, Mathematics, ECE, Python, Economics, ISES, ISCP, and avg).
   • Member functions: add(), display_all(), display_one(), modify(), Delete(), and Grade(float avg).

2. menu() function: It presents a graphical menu-driven interface to the user, allowing them to choose various operations like adding, displaying, modifying, deleting, or exiting the program.

3. Member functions:

   • add(): Allows the user to input student information and calculates the average and grade.
   • display_all(): Displays all student records stored in the "Student.txt" file.
   • display_one(): Displays a particular student record based on the given roll number.
   • modify(): Enables the user to modify an existing student record.
   • Delete(): Allows the user to delete a specific student record.
   • Grade(float avg): Calculates the grade based on the average marks of the student.

4. main() function:

   • Creates an instance of the student class named project.
   • Calls the menu() function to initiate the menu-driven system.
