to allocate memory dynamically to a class

Hi, I saw a program like the following:

*******************************************
class Image
{
public:
...
Private:
...
};

Image * imagePtr;
imagePtr = new Image();
....
delete imagePtr;
*********************************************

Why the sentence is: image = new Image()?

I thought it should be : image = new Image{}.

Thanks

Because the standard says so.

Ok. Youre wrong then - what made you think so?

/Peter

image = new Image;should be ok.
