代碼首先宣告具有預先計算的大小的各種陣列，并將在程式的其余部分中使用。但是，在宣告串列中的某個點之后，即使編譯成功，C 也將無法生成任何輸出。在代碼中間的注釋之后，無法生成任何輸出。我嘗試過像“cout”這樣的簡單輸出并寫入檔案。
編輯：我添加了一個由答案之一撰寫的示例輸出來演示。該程式只是運行并且不會產生任何東西。這是終端輸出：“

您的代碼原樣不會“輸出”任何東西。我編譯并運行了您的代碼，std::cout并在您的評論下方和上方添加了陳述句“在此點向下之后，將不會生成任何輸出”。這成功寫入標準輸出。
例如，如果您想輸出coords陣列中的所有值，您可以在構建它時執行以下操作：
for (int j = 0; j < 2; j ) {
for (int i = 0; i < totalNumMatPoint; i ) {
coord[i][j] = coord_excess[i][j];
std::cout << coord[i][j] << std::endl;
}
}

我使用了另一臺具有不同作業系統（即 Ubuntu）的 PC，它運行良好。不知道是什么問題。可能在第一臺計算機上使用我的編譯器和/或編輯器運行某些東西。
