Function template specialization with a template class [duplicate]

Answer 1

There is a general workaround in which the function-template just delegates the job to class template member functions:

#include 
#include 

template  struct helper {
    static void print(T value) { std::cout << value; }
};
template  struct helper> {
    static void print(std::vector const &value) { }
};

template 
void print (T const &value) {
    // Just delegate.
    helper::print (value);
}


int main () {
    print (5);
    std::vector v;
    print (v);
}

However, if you can come by with simple function overloading (as suggested by ecatmur and Vaughn Cato), do so.
