auto func = std::bind(&MyClass::memberFunction, &myObject, std::placeholders::_1); func(30); // 会调用 myObject 的 memberFunction 方法 4.2.3 综合应用 这些技术可以被用来创建灵活和强大的回调机制,在C++中实现C语言风格的回调。通过结合使用函数对象、std::function和std::bind,我们可以实现一个灵...

編譯器警告 (層級 1,關閉) C4822'member function':區域類別成員函式沒有主體 編譯器警告 (層級 3) C4823'function':使用釘選指標,但未啟用回溯語意。 請考慮使用/EHa 編譯器警告 (層級 2,關閉) C4826從 'type1' 到 'type2' 的轉換是帶符號的延伸。 這可能會造成未預期的執行階段行為。
enum class UrlTableError { kOk = 0, kOutOfMemory, kMalformedInput, }; 宏变量名 C++通常不应使用宏。但是如果使用时,应该全部大写和下划线命名。 #define ROUND(x) ... #define PI_ROUNDED 3.0 全局变量名 C中对全局变量在变量名前加g_作为标识,如:g_value 格式 代码中的每一行文本最多应包含 80 ...

You don't need to use an enum for this; a class type with a size_t member would also work. An alternative solution is that you might be able to eliminate the placement new altogether. If your code uses placement new to implement a memory pool where the placement argument is the size ...
If you also want to have a Decode that expects a byte *, then you have to add that declaration in the class. You can't write any class methods that aren't declared in the class header.Similarly, the class does not declare a RegisterREPM. If you want to have such a function, you...

Is it legal (and moral) for a member function to say delete this?合法,但:必须保证 this 对象是通过 new(不是 new[]、不是 placement new、不是栈上、不是全局、不是其他对象成员)分配的 必须保证调用 delete this 的成员函数是最后一个调用 this 的成员函数 必须保证成员函数的 delete this 后面没有...
