In most cases new actually calls malloc. The real difference is that new can be overloaded, so the user can
change the way it behaves. For example, maintain a private
pool of memory from which new will take memory.

another thing, new doesn't exist in C but only in C++.
You can safely use malloc also in c++, but you must make sure you call "free" to free the memory. When working with new, you must call "delete" to free the memory.

The most importan thing to notice, is that new also calls
the appropriate object constructor while malloc doesn't.
