This is legal (safe) and works with the compilerenvironment I am using:
CMyObject *ptr = NULL; delete ptr;However, I get a run-time error (assert) whenI use the array delete operator:
long *array = NULL; delete  array;Is the environment right or is it legal C++ to use array delete on a NULL pointer?
It is perfectly legal and safe to use delete or delete  on null pointers. When called with a zero argument the operation has no effect.
