  • 例外宣告

    相比于斷言適用于排除邏輯上不可能存在的狀態，例外通常是用于邏輯上可能發生的錯誤。 例外宣告 Item 1：當函式不可能拋出例外或不能接受拋出例外時，使用noexcept 理由 如果不打算拋出例外的話，程式就會認為無法處理這種錯誤，并且應當盡早終止，如此可以有效地阻止例外的傳播與擴散。 示例 //不可 ......

  • C/C++編程筆記：關于C++的參考型別，專供新手入門使用

    今天要講的是C++中我最喜歡的一個用法——參考，也叫別名。 參考就是給一個變數名取一個變數名，方便我們間接地使用這個變數。我們可以給一個變數創建N個參考，這N + 1個變數共享了同一塊記憶體區域。(參考型別的變數會占用記憶體空間，占用的記憶體空間的大小和指標型別的大小是相同的。雖然參考是一個物件的別名，但 ......
