Answer:
The C's malloc and free functions and the C++'s new and delete operators execute similar operations but in different ways and return results.
Explanation:
- The new and delete operators return a fully typed pointer while the malloc and free functions return a void pointer.
-The new and delete operators do not return a null value on failure but the malloc/free functions do.
- The new/delete operator memory is allocated from free store while the malloc/free functions allocate from heap.
- The new/delete operators can add a new memory allocator to help with low memory but the malloc/free functions can't.
- The compiler calculates the size of the new/delete operator array while the malloc/free functions manually calculate array size as specified.

A directory traversal attack or path attack is done through a web browser by an attacker, who seeks for a weak path link on the public's website and accesses the information in the server.
