Need ctor parenthesis with new?

[Disch]

Hey, I just have a quick question regarding C++ standards and the new operator.

If I have a class with a default ctor:

class A
{
  A() { /* Do Stuff */ }
};

Does the C++ standard require I use ctor parenthesis with the new operator? What I mean is this:

A* a = new A;     // is this legal?
A* aa = new A();  // or do I have to do this? 

The reason I ask is that VS6 apparently errors if you don't include the parenthesis -- someone tried to compile one of my programs in VS6 (which compile fine on VS7+) and got errors due to the lack of parenthesis. I know VS6 is not very standards compliant, but it got me to wondering as to exactly what the standard was.

While on the subject -- what about new[]? Is it even possible to use parenthesis with new[]?

Thanks in advance.

Both syntaxes are legal. Not sure about your other question, though.

The standard does not require parentheses.

int* pInt = new int;

is perfectly legal syntax.

array new only allows elements to be default constructed, therefore parentheses are meaningless (and probably not even allowed, but I'm not 100% sure).

Excellent. This is what I thought, but I'm glad to hear confirmation.

Thank you both.
