3 Практическое решение и обоснование программы

Данная задача решена следующим образом: на C++ с использованием Visual Studio 2010 была написана программа, которая получает данные от пользователя в файле с расширением .txt и помещает из них данные в поле textbox, после нажатия кнопки «Выполнить расчет» запускается алгоритм расчета необходимых параметров: радиусы вписанной и описанной окружностей, площадь и периметр треугольника. После этого программа по полученным данным выполняет построение фигур на координатной плоскости. При необходимости все полученные данные можно сохранить в файл с расширением .txt. При нажатии на клавишу «О программе» выводится окно с данными о программе и команде разработчиков.

Рисунок 1 – Пример входных данных.

Рисунок 2 – Процесс работы программы

Рисунок 3- Пример выходных данных

Заключение

В данной работе требовалось написать программу на C++ по выполнению операций описанных в задании.

По введенным данным были построены необходимые геометрические фигуры и данные, являющиеся результатом работы программы, были сохранены в файл. Корректность работы программы была проверена с помощью тестовых расчетов. Тесты показали, что программа работает корректно и без ошибок. К недостаткам можно отнести то, что данная программа строит графики только на плоскости и только для значений, расположенных в определенной структуре в файле c расширением .txt.
