This project aims to simulate an enterprise application system for managing students, their grades, and courses. The system is implemented in C and focuses on inputting and processing student data, course information, and grades. The program allows users to input student and course data, record grades, and generate reports.

typedef struct ucenik {
    int index, brojpredmeta;
    char ime[30], prezime[30];
    struct ucenik *sledeci;
} ucenik;

2. Course Structure (predmet)📚

typedef struct predmet {
    int sifra;
    char nazivpredmeta[30];
    int brojstudenata;
    struct predmet *sledeci;
} predmet;

3. Grade Submission Structure (prijava)📝

typedef struct prijava {
    int brojindeksa, sifra_pred, ocena;
    struct prijava *sledeci;
} prijava;
