[Thomas1965]

int main() 
{
   void Bubblesort();
   system("pause");
   return 0;
}

You declare a function Bubblesort inside main instead of calling it.

From what Thomas1974 said :

==>

int main()
 {
   void Bubblesort<???>();
   system("pause");
   return 0;
 }

[Naughty Albatross]

template<class T>
void Bubblesort(){}

This template function has one template parameter <class T>, meaning it requires at least one argument. Simply calling Bubblesort() will not work. You must supply the <class T> in order to be able to call this function.

For example :

Bubblesort<int>();
Bubblesort<double>();

Does that help you? :)
