    int totMarks;
};

int main() {
    Student students[10] { {12345, "John Dow", "CSE123", 2020, 234},
                           {12355, "Adam Smith", "EC222", 2020, 233},

    ofstream ofs("students.txt");
    for (int i=0; i<10; i++) {
        ofs << students[i].rollNo << endl;
        ofs << students[i].name << endl;
