copy constructors for template classes

[stmfc]

what is the difference between this two versions of copy constructors:

myClass(const myClass & mc);
myClass(const myClass<T> & mc);

here is the template class declaration:

template<class T>
class myClass {
private:
        T val;
public:
        myClass(T v=0);  // default constructor
        //myClass(const myClass & mc);  //copy constructor version1
        myClass(const myClass<T> & mc);  //copy constructor  version2
        void display() { cout<<"val: "<<val<<endl; }
};

There isn't.

Inside a class you can use both className<T> or className. There's synomym.

Template is very powerful. What you can also do is something like:

template <class T1>
class c
{
template<T2>
c( c<T2> const & ); //you can copy c<int> into c<long> for example.

};
