Hi, this question is related to this one . Given this code
char *p = new char[200]; delete[] p;
what would happen if you set p[100] = '\0' before deleting p?

The presence.
It's really no different than say deleting an array of int's.

Using a NULL.
There's no reason to check for null before deleting it if it's at all possible that some knucklehead can attempt to use the pointer.

Windows seems to have a length limit on file names when trying to delete, though it won't prevent those files from being created.
