C++ templates specialization syntax

Question

In C++ Primer Plus (2001, Czech Translation) I have found these different template specialization syntax:

function template

template         


        

Answer 1

Using Visual Studio 2012, it seems to work slightly different if there's no function argument:

template  T bar( );
//template int bar( ) { return 0; } doesn't work
template < > int bar( ) { return 0; } //does work
