求指点迷津.

#include<iostream.h>
template<class T1,class T2>
class myclass{
    public:
        myclass(T1 a,T2 b)
        {i=a;j=b;}
        void show()
        {cout<<i<<' '<<j<<'\n';
        }
    private:
        T1 i;
        T2 j;
};
int main()
{ myclass <int,double>ob1(10,0.23);
myclass<char,char*>ob2('X',"this is a test.");
ob1.show();
ob2.show();
return 0;
}
