new
returns a pointer to the allocated memory
|
|
 |
|
|
|
|
|
|
The
storage duration of the new object is
from the point
|
 |
|
|
|
of creation
until the operator delete destroys it by
|
|
|
deallocating its
memory, or until the end of the
|
|
|
program.
|
|
|
|
By
default, an allocation failure (such as insufficient or
|
|
 |
|
|
|
|
|
fragmented heap
memory) results in the predefined
|
|
|
exception
bad_alloc being thrown.
|
|
|
|
You
should use the delete operator to remove all
|
|
 |
|
|
|
|
|
memory which
has been allocated by the new operator.
|
|
|
Failure to free
memory can result in memory leaks.
|
|
|
|
The delete operator offers dynamic storage
|
|
 |
|
|
|
|
|
deallocation,
deallocating a memory block allocated by a
|
|
|
previous call to
new.
