template template parameter issue

[SamWo123]

I am wondering what's wrong with template parameter in print()?
I was tring to use print without specifying template argument.


This is the error I got.
error C2784: 'void print(const C<T> &)' : could not deduce template argument for 'const C<T> &' from 'std::vector<_Ty>'

#include <vector>
#include<iostream>
#include <iterator>
using namespace std;

template<typename T, template<class > class C >
void print(const C<T> &x) 
{
	copy(x.begin(), x.end(), ostream_iterator<T>(cout," "));
	cout << endl;
}

int main()
{
   vector<double> v;
   v.push_back(100);
   print(v);

}
