Syntax of out-of-class definition of a template member function of a template class

问题

template<typename A, typename B>
class mindF_ck
{
    template<typename C>
    inline bool ouch(C & c_in);    
};

How do I define the signature for ouch out-of-class ? I send a query to my brain but it keeps coming up blank ;)

回答1:

template<typename A, typename B>
template<typename C>
bool mindf_uck<A,B>::ouch(C & c_in) {
}

回答2:

template <typename A, typename B>
  template <typename C>
bool mindf_ck<A, B>::ouch(C& c_in) {
    // ... code ...
}
