Windowsアプリ開発＿電卓

Visual C++で、一番初めに電卓を作ってみる。
　

「カシオ計算機 CASIO 学校専用電卓 12桁 AZ-26S」というものが標準らしいので、この電卓に近づける感じで作っていく。

　

電卓の使い方

電卓の機能はこのページで確認できる。
カシオの電卓シュミレーター - 電卓を体験しよう - 電卓 - CASIO
履歴と「GT（グランドトータル）」機能 - なにしろ電卓の使い方
Web電卓／計算機アプリ（消費税学習機能・スマホキー配列）| 電卓アプリ
他にも、Googleで「電卓」と調べればGoogle電卓がすぐに使えるし、「web電卓」という名のインストール不要のブラウザ電卓が複数ある様子。
　
　

使用した関数

プログラミング！！

第６講 簡易電卓ソフト作りに挑戦しよう 第１話 簡易電卓Form1作り
　
上記サイトを参考に作成。

　
　
はっきりいって、自分で試行錯誤やるしかない。が、ロジック的な部分に苦戦した。
関数や電卓の動きについて調べるのにも時間を要した。その辺は自分の努力しだいとは違うので、上記サイトなどを参考にするとよいのではと思う。
　
また、一応下記にソースを記載するが、おそらく無駄な処理が多い。途中で少し飽きてきてしまったこともあり、表面的にしか動きを確認していないので、おそらく不具合が起こると思われる。（自己責任でお願いいたします。）あくまでも参考に。
　
大事なのは、電卓の作りたい機能をどうやって実現するのか自分で考えること、だと思う。
特に（自分も含め）慣れないうちは、効率や無駄など考えずに、同じ結果になることだけをまず追求すべきだと思う。実際、想定した動きになったときに喜びは大きい。
というのが、はじめてGUIアプリを今回作ってみての感想。
