大学のプログラミングコースで取り組んでいるすべてのプログラムを紹介します。割り当ての要件を完全に満たすまでにはまだ少し道のりがありますが、プログラムの基本的なドラフトをエラーなしで取得し（おそらく）、実行されているように見えます...しかし、突然Xcodeのデバッガーにアクセスして自分：
Thread 1: EXC_BAD_ACCESS(code=2, address=0x7fff95c1e5f5)
これが私を追い出すまでのコマンドライン出力です：
-----------------------
Quarterly_sales_taxator
-----------------------
How many company divisions will we be dealing with? 2
Am I correct in assuming that there are 4 sales quarters? yes
Please enter the sales Company Division #1 brought in for Sales Quarter #1 20
