for object, malloc allocates memory in heap however doesn't invoke object's constructor to initialize the object. new allocates memory & also invokes constructor to initialize the object. free() and malloc() do not support object semantics, does not destruct and construct objects
For example : string * ptr = (string *)(malloc (sizeof(string))) Are not secure, and does not compute the size of the objects that it construct
The following return a pointer to void int *p = (int *) (malloc(sizeof(int))); int *p = new int;
Are not extensible delete and new can be overloaded in a class "delete" first calls object's termination routine (for example. its destructor) and after that releases the space the object engaged on the heap memory.

Int_t *my_ints = new Int_t[10];
...
delete []my_ints;
