ThisClass () statement causes a stack overflow

I want the class to be simple and not define a constructor, so I can make the data Pt = {0, 5}; so I figured the best way to convert Pt_t from short to long or vice versa is to do something like this.

template <class T>
struct Pt_t
{
    T x, y;
    template <class T2> operator Pt_t<T2>() { Pt_t pt = {x, y}; return pt; }
};

The compiler dislikes this and calls the Pt_t operator when it returns pt; thus getting a stack overflow. How can I prevent this? the only solution I can think of is that Pt_t uses constructors that remove Pt_t pt = {1, 2}; which I prefer to keep if I can.

I'm sure there is an unqualified Pt_t in your function body Pt_t<T>

, but don't you want it to be Pt_t<T2>

? You will need to explicitly qualify it.

I'm not familiar with C ++, but are you declaring the correct type in your method?



Shouldn't it be Pt_t<T2>

instead Pt_t

?
