如果错误消息指出在调用myFunction时发生了"expected nested-name-specifier before"错误,那么很可能是因为忘记使用myNamespace::前缀。正确的方式是myNamespace::MyClass obj;,并且在调用成员函数时也应该确保作用域正确。 如果错误发生在其他地方,比如使用了错误的命名空间或类名,你需要根据具体的错误消息和代码上下文来修正。

在C++编程语言中,"used in nested name specifier"这个表述通常与作用域解析有关。作用域解析是指在程序中确定一个标识符(如变量、函数、类等)的具体位置和含义的过程。嵌套名称说明符(nested name specifier)用于指定一个标识符所属的嵌套作用域。 基础概念 ...
而在B.h中又使用了A.h中定义的模版,因此也需要#include "A.h"(即,又需要知道A的定义) 头文件相互包含,不但要用到#include,而且还要分别声明要用到的类。 比如A.h中,添加#include"B.h",而且要添加class B;B.h中也是一样,否则就报错。
