（「|」で区切られた）ファイルから入力を受け取る小さなプログラムを作成しようとしています。たとえば、ファイルの1行は次のようになります。
name|phone|address|city|state|zip
何らかの理由で、構造体の配列にあるすべてのものをバイナリファイルに書き込もうとするたびに、配列のリンクが失敗します。私はこれを数時間見てきましたが、なぜこれが行われるのか理解できません。私が気付いた問題の1つは、プログラムを実行することにし、インデックス1に何かを書き込んだ後、配列のインデックス0にあるものを出力すると、インデックス0が台無しになることです（各インデックスは構造体を保持します）。理由はわかりません。
助けてください、私は何時間もキーボードに頭をぶつけて、なぜそれが私にこの問題を引き起こすのかを理解しようとしています。申し訳ありませんが、最初のパラメータをファイルへのパスとして実行する必要があることを忘れてしまいました。例：./ExerciseOne.out /path/to/file.txt
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
