有多种方法会导致此错误。 通常是由编译器无法理解的令牌序列引起的。 示例 在此示例中,强制转换运算符与无效运算符一起使用。 C++ // C2760.cppclassB{};classD:publicB {};voidf(B* pb){ D* pd1 =static_cast<D*>(pb); D* pd2 =static_cast<D*>=(pb);// C2760D* pd3 =static_cast<D...
本部分列出的文章描述了 Microsoft C/C++ 编译器警告消息 C4800-C4999。 重要 Visual Studio 编译器和生成工具可报告多种类型的错误和警告。 发现错误或警告后,生成工具可做出有关代码意向的假设并尝试继续,因此,可能会同时报告更多问题。 如果工具做出错误假设,则后续错误或警告可能不适于你的项目。 纠...

You'll also need to update the calls to placement new to pass the new type (for example, by using static_cast<my_type> to convert from the integer value) and update the definition of new and delete to cast back to the integer type. You don't need to use an enum for this; a ...

To support functions such as printf(), the syntax for prototypes includes a special ellipsis (...) terminator. Because an implementation might need to do unusual things to handle a varying number of arguments, ISO C requires that all declarations and the definition of such a function include ...
