//以下代码用VC6编译会出现错误error C2893，但用VS2008则编译通过。//VC6必须将成员函数声明和实现一起放入类定义中才能编译通过。//VC6爱与恨的纠结。//结论：用C++标准的东东就不要用VC6。//TemplateEx.h#include "stdafx.h"class APP{public:template<class T>int Fun1(T& t);template<class T>int Fun2(T& t);};//TemplateEx.cpp#include "stdafx.h"#include "TemplateEx.h"template<class T>int APP::Fun1(T& t){return t + 8;}template<class T>int APP::Fun2(T& t){return Fun1(t) + 6;}int main(int argc, char* argv[]){int y = 17;APP app;int x = app.Fun2(y);printf("x=%d/n",x);return 0;}//修改后的TemplateEx.h#include "stdafx.h"class APP{public:template<class T>int Fun1(T& t){return t + 8;}template<class T>int Fun2(T& t){return Fun1(t) + 6;}};//修改后的TemplateEx.cpp#include "stdafx.h"#include "TemplateEx.h"int main(int argc, char* argv[]){int y = 17;APP app;int x = app.Fun2(y);printf("x=%d/n",x);return 0;}
