Does space reserved by new automatically get deleted at prog end?

Does the space you reserve with the 'new' operator automatically get
returned to the system when the program ends?

That's operating-system specific.

Depends on your OS. AFAIK, most of your modern, garden variety OSes will
behave this way though.

Depends, but if you're asking that question, I would say no. That's why
there's a delete operator.

As others pointed out, OSes _usually_ do that for you. But note that they
won't call your objects' destructors, so if you have e.g. cached any data
to be written to disk on object destruction, that data will be lost, or
network connections might not be shut down properly, but just terminated
instead, ...

as others have pointed out, the OS may, but it's just good practice to
keep track of everything you allocate and deallocate it when you don't
need it anymore...

In addition to what others have said: It's very good policy
to program cleanly, because a chunk of code won't necessarily
always be a stand-alone program. If your code does not tidy
after itself, then gets put in a library, it will be a memory
leak. And people will be upset with you.
