Is it legal to declare multidimensional array like that?
int *a=new int[5,5,5,5];
It translated without an error.

Thanks. I'm just wondering why did they do that? Very strange.

You can only pass one parameter to the operator function. It is actually read like this (because the comma is also an operator):
int *a= new int[ (5,5,5,5) ];
So the last value will be what it actually takes as a parameter.
To allocate a multi-dimension array you do it like this:
int (*a) = new int;

int[5,5,5,5] is not a multidimensional array. It is a one-dimensional array the size of which is specified with an expression using the comma operator..
To declare a multidimensional array you should write
