constructor for POD types?

[George2]

Hello everyone,


When implementing a general template class, sometimes we call T() -- suppose T is type argument of a template class.

My questions,

1. what will happen if T is POD type? Do nothing?

2. Is it good code? Or working but not good code?

Here is my test code, works in MSVC 2008.

template <class T> class Foo {
public:
	void static test()
	{
		T(); // call constructor for any type, including POD?
	}
};

int main()
{
	Foo<int> g;

	g.test();

	return 0;
}

thanks in advance,
George
