無法存取 『function』 候選函式類別中定義的friend函式不應該被視為在全域命名空間範圍中定義和宣告。 不過,它可以透過自變數相依查閱找到。C3767 也可能因為重大變更所造成:原生類型現在在 /clr 編譯中預設為私用;如需詳細資訊,請參閱類型可見性。範例
In this case, the non-member function must be designated as a friend function of the class. Thus the friend function be able to access all members of the object, even protected members of the base class of the object. The friend function declaration form is as shown below: ...
Compiler error C3637 'function': a friend function definition cannot be a specialization of a function template/generic Compiler error C3638 'operator': the standard boxing and unboxing conversion operators cannot be redefined Compiler error C3639 a lambda that is part of a default argument can on...
宁以non-member、non-friend 替换 member 函数(可增加封装性、包裹弹性(packaging flexibility)、机能扩充性) 若所有参数(包括被this指针所指的那个隐喻参数)皆须要类型转换,请为此采用 non-member 函数 考虑写一个不抛异常的 swap 函数 尽可能延后变量定义式的出现时间(可增加程序清晰度并改善程序效率) 尽量少做转型...
having external linkage.(22)false,truebool类型的两个枚举值.(23)float声明浮点型变量或函数.(24)for一种循环语句(可意会不可言传).Use the for statement to construct loops that must execute aspecified number of times.(25)friend声明友元函数或者类.The friend keyword allows a function or...

The standard requires that if the use of a placement new looks up a corresponding delete function and finds a usual deallocation function, the program is ill-formed. For example, suppose your code defines both a placement new and a placement delete: C++ Copy void * operator new(std::size...
它包含了C的全部特性以及面向对象的一切，然后又发明了模板、大搞元编程（meta program）和编译期计算，...
