Answer 1

`delete` here meant to tell the big boss (operating system) that your program no longer need that block of memory, and big boss can then re-offer that block to be used by another program. But it isn't necessary that you cleanup the block (zero fill the block). It's as if when you rent an apartment, you may have some of your stuffs left in there when you leave the apartment. There's no obligation for you to make sure that the apartment is clean for the next people to live in. All that is required of you is to state that you will no longer extend your stay, which is done by informing the building management. In code, that is the `delete` statement.
