Use new and new[]. Difference is, new is type safe and calls
constructors for classes/structs, malloc is/does none of that.

malloc allocates storage
new allocates storage and constructs an object in that storage

So the question: 'which one is better?' makes no sense - they
do different things.

and doesn't throw an exception. As for "new", it's all in the
declarations (placement and array functions aside for a moment):

void * operator new(std::size_t size) throw(std::bad_ alloc);
void * operator new(std::size_t size, const std::nothrow_t &) throw();

Nah, new-expression is hardly related to malloc(). ;-)
