在C程序中,静态初始化顺序失败是一个可能的问题,尤其是在涉及多个源文件和静态变量初始化的情况下。静态初始化顺序失败通常发生在以下情况: 跨文件依赖:当一个源文件中的静态变量依赖于另一个源文件中的静态变量时,可能会出现初始化顺序问题。因为编译器和链接器无法保证这些静态变量的初始化顺序。 循环依赖:如果...

这个示例代码中,一个SuperClass实现了+(void)load和+(void)initialize方法(实际上应该算是重写覆盖了NSObject的这两个方法);ChildClass继承于SuperClass,但是只重写+(void)initialize没有+(void)load;Insideinitialize类也有+(void)load和+(void)initialize方法,它在ChildClass的i+(void)initialize方法中被构建出一个...
enum class my_type : size_t {}; 然后,更改对 placement new 和 的定义,以使用此类型作为第二个自变量(而不是 delete)。size_t 你还需要更新对 placement new 的调用以传递新类型(例如,通过使用 static_cast<my_type> 从整数值转换)并更新 new 和delete 的定义以强制转换回整数类型。 你无需为此使用 ...
