    if (fp == NULL) {
        printf("Error opening file! ");
        exit(1);
    }

    printf("Enter the number of MCA students: ");
    scanf("%d", &count);

    for (int i = 0; i < count; i++) {
        printf("Enter details of student %d ", i + 1);
        printf("Enter roll number: ");
        scanf("%d", &students[i].roll_number);
