非模板类,可以有模板函数么?解决方案

非模板类,可以有模板函数么?
我用VC8编译下面的代码提示错误:

C/C++ code

#include "stdafx.h"class my{public:    my():i(2),j(3){printf("ctor\n");}    ~my(){printf("dtor\n");}    template<class T>    vod add( T t ){        i+=t;    }private    int i,j;};int main(int argc,char**){    my m1;    m1.add<short>(3);    return 0;}

1>my.cpp(17): error C2065: 'm1' : undeclared identifier

如果我在class 前面加上模板声明
template<class U>
使用的时候变成my<int> m1;
这次错误更多了

1>my.cpp(9): error C2146: syntax error : missing ';' before identifier 'add'
1> my.cpp(14) : see reference to class template instantiation 'my<U>' being compiled

到底错在哪里呢?

[解决办法]
显然是可以的嘛。楼主敲代码要小心啊。

C/C++ code

class my{public:    my():i(2),j(3){printf("ctor\n");}    ~my(){printf("dtor\n");}    template<class T>    void add(T t ){        i+=t;    }private:        int i,j;};int main(int argc,char**){    my m1;    m1.add<short>(3);    return 0;}
