In C, there are no destructors to call. The developer has to handle the
uninitialization of his objects himself.

In C++, it is important to know if a pointer points to a single object or
to an array of objects. If it points to an array, for every one delete []
invokes the object's destructor.

Because new and delete are C++ operators in the language and malloc is a
function call.
