再次请教关于error LNK2005的问题！急！
前几天这个帖子在论坛里发过了，但现在仍然没能解决，帖子很快就成下去了，因此决定重发一次，还往斑竹能够手下留情！编程时遇到一个关于error LNK2005的问题，不知道那位高手能帮我解决！不胜感激！
我定义了两个类，geo和coe。两个类的成员数据和成员函数的申明分别写在两个文件里，"geometrical.h","coeffcient.h"和"geometrical.cpp"和"coeffcient.cpp"。
同时，class coe: private geo
{
……………………
}
在每个".cpp"文件的开头都#include 对应的".h"，如下所示（coe.cpp有所不同）
//geometrical.cpp
#include "geometrical.h"
………………
………………
//coeffcient.cpp
#include "geometrical.cpp"
#include "coeffcient.h"
………………
………………
最后在main()里：
#include "coefficient.cpp"
编译通过了，但在link时发生了如下的错误：
geometrical.obj : error LNK2005: "public: __thiscall geo::geo(double,double,double,int,int,int)" (??0geo@@QAE@NNNHHH@Z) already defined in coefficient.obj

Debug/test1.exe : fatal error LNK1120: 1 unresolved externals
每个头文件里都写了语句#pragma once，但仍然出现这种错误。
我又在每个头文件里写了
#ifndef ***.h
#define ***.h
………………
#endif
但还是不行。
小弟为VC++菜鸟，还往那位高手不惜赐教！万分感谢！
