Thread: Allocation error throwing

What is the best way to deal with memory allocation errors? Do some compilers throw an exception and others return null?

Code:

try
 {
     int * x = new int[10];
}
catch (bad_alloc)
{
   cout << "out of memory" << endl;
}

OR

Code:

int * x = new int[10];
if(x == NULL)
    cout << "out of memory" << endl;

I feel one is C++ and the other C.
