?new? is used for dynamic memory allocation in C++,
?malloc()? is used for dynamic memory allocation in C.
?new? allocates memory on heap.
?malloc()? allocates memory on heap.
?new? is operator,
?malloc()? is function
?new? returns memory pointer to the correct object on
SUCCESS,
?malloc? returns pointer to void void* on success
?new? throws exception called ?bad_alloc? on FAILURE,
?malloc? returns NULL on FAILURE
?new? is 2 step process
(i) First Allocates memory for a given object
(ii) Calls corresponding destructor if required
?malloc? is one step process ie it allocating only memory.
