Why wont this compile

template <class t>
struct a
{
a(t& ty=t() ,a* p=0):o(ty),n(p){}
t& o;
a* n;


};

What are the errors?

Correction: It WILL compile.
If it doesn't compile for you, then you must be getting errors somewhere, and I doubt it is with this piece of code (unless your compiler is out of date).

A temporary object can't bind to a non-const reference.

It works in Visual Studio.

It works in Visual Studio.

If your definition of "works" is "the compiler doesn't complain if I don't instantiate an instance," then yes, it "works."

template <class t>
struct a
{
a(t& ty=t() ,a* p=0):o(ty),n(p){}
t& o;
a* n;
}; 

int main()
{
    a<int> c ;
}
