char* arr = “Nisse”; ?

[d00ape]

Exactly what happens if I write:

char* arr = “Nisse”;

Can I run:

delete arr;

Or

delete [] arr;

What is the best thing to do?

A1: No, you can't, because of arr pointer refers to a static storage of "Nisse" string literal (it may be write-protected storage or not, but it's not a dynamic storage from the heap)...

A2: See above...

A3: The best solution: Do nothing to delete string literal via its pointer!

delete arr;
Should follow an arr=new something. You dont do any new, so...

delete [] arr;
Should follow an arr = new something[...]. You dont do any new [...], so...

If you like at the end of your program you can do:

arr = 0;

Thats a way of making sure the pointer is 'NULL'ed and put in a nice consistant state before exiting your program.

keyword 'delete' only needs to be used if you use the keyword 'new'.
