At the same time I dontunderstand why r u defining the body of the functions within headerfiles like u did in Implementation.h. As far as my knowledge goes ".h"files are for declaring function prototypes and variables only. We dontwrite the body of the function within a header file. That might be thereason why r u getting this compilation error.blueblueblue2005 wrote:这是我从Deitel C ++复制的一个例子书。但是当我编译它时，总是得到上面的编译错误，无论我如何更改包含顺序，请帮忙。 这里是文件：注意：这是练习代理类。 // Implementation.h 类实现{ public： Implementation（int v）{this - > v = v; } void setValue（int v） { this-> v = v; } int getValue（）const {返回v; } 私人： int v; }; // Interface.h 类接口{ public： Interface（int）; ~Interface（）; void setValue（int）; int getValue（）const; 私有：实现* ptr; }; / *接口.cpp * / #include" Implementation.h" #include" Interface.h" Interface :: Interface（int v）：ptr （新的实现（v）） {} 接口:: ~Interface（）{delete ptr; } void Interface :: setValue（int v）{ ptr-> setValue（v）; } int接口:: getValue （）const { return ptr-> getValue（）; } / * t.cpp * / #include< iostream> ; 使用命名空间std; #include" Interface.h" #include" Implementation.h" int main（）{接口i（5）; cout<< i.getValue（）<< endl; i.setValue（19）; cout<< i.getValue（）<< endl; 返回0; } ＃============这是Makefile ＃Makefile a。 out：Implementation.h Interface.h Interface.cpp t.cpp g ++ Implementation.h Interface.cpp t.cpp clean： rm -f a.out cleanall： rm -f * .h * .cpp a.out Hi, here is an example I copied from Deitel C++ book. but when I compile it, always get the above compilation error, no matter how I change the include order, please help. here is the files: Note: this is to practice Proxy classes. // Implementation.h class Implementation { public: Implementation(int v) { this->v = v; } void setValue(int v) { this->v = v; } int getValue() const { return v; } private: int v; }; // Interface.h class Implementation; class Interface { public: Interface(int); ~Interface(); void setValue(int); int getValue() const; private: Implementation *ptr; }; /* Interface.cpp */ #include "Implementation.h" #include "Interface.h" Interface::Interface(int v):ptr(new Implementation(v)) { } Interface::~Interface() { delete ptr; } void Interface::setValue(int v){ ptr->setValue(v); } int Interface::getValue() const { return ptr->getValue(); } /* t.cpp */ #include <iostream> using namespace std; #include "Interface.h" #include "Implementation.h" int main(){ Interface i(5); cout << i.getValue() << endl; i.setValue(19); cout << i.getValue() << endl; return 0; } # ============ this is Makefile # Makefile a.out: Implementation.h Interface.h Interface.cpp t.cpp g++ Implementation.h Interface.cpp t.cpp clean: rm -f a.out cleanall: rm -f *.h *.cpp a.out blueblueblue2005写道：blueblueblue2005 wrote:这是我从Deitel C ++书中复制的一个例子。但是当我编译它时，总是得到上面的编译错误 Hi, here is an example I copied from Deitel C++ book. but when I compile it, always get the above compilation error [snip] 什么错误？消息正文中没有包含错误。确保 确保将您的问题包含在邮件的*正文*中，而不仅仅是主题行 。 /丹[snip]What error?
