Общее условие задачи:
- Представьте заданную таблицу в виде файла БД, выберите тип поля и его разрядность.
- Напишите программы создания файла добавления в него записей, удаления записей, исправления записей, вывода содержимого файла на экран в виде таблицы и просмотра этой таблицы страницами, двигаясь вверх и вниз по записям, по страницам, сразу перемещаясь к началу или концу файла.
- Напишите программу, которая сортировала бы файл по любому указанному полю.
- Напишите программу, которая отыскивала бы и выводила для просмотра записи файла найденные по заданному логическому выражению, содержащему поля файла, числа, операции.
- Напишите программу, которая бы объединяла все выше описанные программы с помощью комбинированного меню в единую систему.

Решение данной задачи разделим на два основных блока. Первый написание программы, которая создает файл базы данных и заносит данные. Второй написание программы, которая работает с готовым файлом дынных. Работу организуем с бинарными файлами. Первая программа будет запрашивать у пользователя имя файла, если такой файл уже существует то она выведет на экран его содержимое, в противном случае создаст новый и запросит у пользователя количество записей, после чего перейдет к воду данных. Вторая программа выполняет следующие задачи:

FILE *f;
char s[20];
cout<<"imya faila = ";
cin.getline(s,20);

Вариант 2. Автор решения: Федотова Е., группа 121МИ, 2008 год.
1. Сведения о потреблении
1. фамилия потребителя
2. номер потребителя
3. прежнее показание расходомера
1. литера
2. трехзначное число
4. новое показание расходомера
1. литера
2. трехзначное число

Файл создается с помощью структур:
struct pokaz
{char litera;
int chislo;};
struct new_pokaz
{char litera;
int chislo;};
struct potreb
{char fam[20];
int nomer;
struct pokaz p;
struct new_pokaz n_p;};
Задается количество потребителей и заполняется файл. Добавление происходит в конец файла и файл открывается на дозапись (a+b). Редактирование осуществляется постановкой указателя файла на позицию изменяемой записи и записывается новая запись. Удаление осуществляется при использовании дополнительного файла. Сортировка методом вставки происходит с помощью сравнения строк и перемещения меньшей строки в начало, а большей в конец. Поиск записи происходит сравнением указанной строки с записью и сравнением их значений. |

Решение программы организовано таким образом, что сначала заполняется файл данными, потом файл считывается и выводится на экран. Строим меню из 5 пунктов: добавить, удалить, редактировать, сортировать, поиск по условию, печать файла. Сортировка осуществляется методом пузырька. Используемые процедуры: int col(FILE *file); - подсчет количества строк в файле Schet Pole(FILE *file,int k); - читается из файла стодбей для сортировки void record(FILE *file,int i, Schet dat); - перезапись строки в файле при сортировке void print(Schet vsp); - печать файла void print_2(FILE *file); - печать файла |

Решение данной задачи разделим на два основных блока. Первый написание программы, которая создает файл базы данных и заносит данные. Второй написание программы, которая работает с готовым файлом данных. Работу организуем с бинарными файлами. Первая программа будет запрашивать у пользователя имя файла, если такой файл уже существует то она выведет на экран его содержимое, в противном случае создаст новый и запросит у пользователя количество записей, после чего перейдет к вводу данных. Вторая программа выполняет следующие задачи: - добавление записи; - удаление записи; - редактирование записи; - поиск записи по полю и заданному значению; - сортировка файла по выбранному пользователем полю (Выполняет сортировку выбором записей в файле. Файл открывается для чтения и записи. Запрашивается у пользователя номер поля, по которому предполагается ввести сортировку. В алгоритме сортировки при сравнении элементов сравниваем элементы в зависимости от выбранного поля сортировки. После выполнения сортировки функции передается 1, если сортировка выполнена удачно и 0 в противном случае. В конце работы закрываем файл); - просмотр отдельных записей;

Файл создается с помощью структур:
struct tek_sost
{int r;
int p;};
struct bank
{char fio[11];
int n_s;
struct tek_sost t_s;};
Добавление данных происходит в конец файла, т.е. fopen(a+b) .
При удалении данных используем дополнительный файл.
Редактирование осуществляется постановкой указателя файла на позицию изменяемой записи и записывается новая запись.
Сортируем записи путем сравнения строк и перемещения большей строки в конец файла.
Поиск записи происходит по одному из значений записи.

Представляем заданную таблицу в виде БД, создаём файл с возможностью добавления, удаления, исправления,
вывода содержимого в виде таблицы и быстрого перемещения по нему, описываем сортировку по любому указанному полю,
описываем поиск записей в файле по заданному логическому выражению.
Решение данной задачи разделим на два основных блока. Первый написание программы, которая создает файл базы
данных и заносит данные. Второй написание программы, которая работает с готовым файлом данных.

В первой части программа создаёт файл БД и заносит данные. Во второй части программа работает с готовым файлом БД: - добавление записи (с использованием дополнительного файла); - удаление выбранной записи (с использованием дополнительного файла); - исправление выбранной записи (с использованием дополнительного файла); - вывод содержимого БД на экран; - сортировка по выбранному полю (методом вставки: сравнение строк и перемещение меньшей строки в начало, а большей в конец); - поиск по выбранному полю. |
