A Complete Guide to Programming in C++ 筆記
1.c++程式編譯過程。包括兩個階段,compiler和linker。第一個階段compiler是把c++檔案編譯成obj檔案。第二個階段是linker把多個obj檔案和lib檔案生成可執行檔案。明白這個過程,對除錯程式很有幫助,能夠幫你確認問題發生在哪個階段。比如提示syntaxerror,那就是comiler階段出問題了,你原始碼有問題,改改改。
2.c++原始檔一定要儲存為正確的副檔名,一般是cpp或者cc。
3.cin和cout箭頭方向怎麼區分?箭頭方向代表資料流動的方向。cin是一個輸入裝置,cout是一個輸出裝置。你要從輸入裝置中獲取輸入,那麼資料是從cin流向你定義的變數,自然是cin>>temp
如果你要輸出資料,那麼就需要把你定義的變數送給cout,自然是cout<<temp。
4.#includeiostream 中的#表示預處理命令。常見的預處理命令有 #include #define等。

Effective C++ 筆記 —— Item 50: Understand when it makes sense to replace new and delete.
Let\'s return to fundamentals for a moment. Why would anybody want to replace the compiler-provided versions of operator new or operator delete in the first place? These are three of the most common r
Effective C++ 筆記 —— Item 51: Adhere to convention when writing new and delete.
The return value part of operator new is easy. If you can supply the requested memory, you return a pointer to it. If you can\'t, you follow the rule described in Item 49 and throw an exception of typ

Many programmers routinely ignore compiler warnings. After all, if the problem were serious, it would be an error, right? This thinking may be relatively harmless in other languages, but in C++, it\'s
