This project was created as a university homework task. The program is written in C and is designed to manage student data, including calculating scores and identifying students who need to retake exams or assignments.
The project consists of a C program that reads student data from a file, processes the data to calculate various scores, and then provides several functionalities such as listing students, generating retake lists, and displaying rankings.
main.c: The main program file containing all the functions and logic.mintafajl2.txt: The input file containing student data.zhPot.txt: The output file listing students who need to retake exams.hfPot.txt: The output file listing students who need to retake assignments.debugmalloc.h: Header file for custom memory allocation functions.
Csoport: Structure to hold group data.Hallgato: Structure to hold student data, including personal details, scores, and retake requirements.
hozzaadHallgato(Hallgato *head, Hallgato *uj): Adds a new student to the list.adatokBeolvasasa(Hallgato **head): Reads student data from the input file.adatokFelszabaditasa(Hallgato *head): Frees allocated memory for student data.kiirLista(Hallgato *head): Prints the list of students.pontszamokSzamolasa(Hallgato *head): Calculates the scores for each student.compare,compareK,compareN,compareHF: Comparison functions for sorting.listaTombbe,listaTombbeN,listaTombbeK,listaTombbeHF: Functions to copy list data to arrays for sorting.kiirTomb,kiirTombN,kiirTombK,kiirTombHF: Functions to print sorted rankings.potlasEllenorzes(Hallgato *head): Checks which students need to retake exams or assignments.zhPotlasKiiras(Hallgato *head): Writes the list of students who need to retake exams to a file.hfPotlasKiiras(Hallgato *head): Writes the list of students who need to retake assignments to a file.
The main program reads the student data from the input file, calculates the necessary scores, and then provides a menu for the user to interact with. The menu allows the user to:
- Print the list of students.
- Generate a list of students who need to retake exams.
- Generate a list of students who need to retake assignments.
- Display rankings based on different criteria.
- Exit the program.
- Ensure that the input file mintafajl2.txt is present in the same directory as the executable.
- The program dynamically allocates memory for student data and frees it at the end of the execution to prevent memory leaks.
