Тема: Создание приложения «Калькулятор»

Цель. Научиться создавать аналоги стандартных приложений Windows

План работы

1. Повторить примеры и выполнить задания

2. Ответить на контрольные вопросы

приложение калькулятор windows прототип

3. Контрольные вопросы

1. Что такое прототип приложения?

Прототип приложения это пример программы, которую можно улучшить, исправить на ранних этапах.

2. Напишите три программы, в которых можно нарисовать прототип.

GIFFY, XMIND, CACOO, CREATELY.

Вывод: Я научилась создавать аналоги стандартных приложений Windows
