さまざまなパーツを削除して構築しようとしましたが、lnk2019エラーが消えたり、通常のエラーが発生したりすることはありません。

現時点では、すべてが1つのファイルに含まれています（後で終了することはありません）。プログラムには3つの単語リストがあり、それらから専門用語を作成します。単語の追加、単語の削除、リストの表示、デフォルトの復元、ファイルへの変更の保存、ファイルからの変更の読み込みができるはずです。

による問題gccは、関数の正しいインクルードを宣言していないことですrand()-私が追加#include <cstdlib>したところ、問題は消えました。

これを行ったメイン関数にも追加する必要があります。

cin >> mainselection;
if ( mainselection == 1 )

これは機能しません。Mainselection は文字列であり、次のようにクラスの比較メソッドを使用してのみ比較できます。

cin >> mainselection;
if ( mainselection.compare("1") )

等しい場合は 0 を返します。

また、std::vectorC++ で動的サイズの配列を非常に簡単に使用できる場合は、項目をベクトルの後ろにプッシュし続けるだけです。制限をハードコーディングする必要がないことを意味します。

あなたを助けるためのいくつかの提案：

  • 107 行目: if(num4 = 0)(代入演算子) はif(num4 == 0)(演算子と等しい) である必要があります。
  • 260 行目: の後にセミコロンがありませんcin >> mainselection。
  • 261 行目:if(mainselection == 1)不正でmainselectionあり、std::string.
  • 284 行目: C++ で関数を再帰的にif(makeselection == "2") main();呼び出すことはできません。main()
