Deleting a pointer...

[kk]

What happens if we delete a pointer twice ? Does the program always
crash or the behavior is undefined ?

Undefined Behaviour.

Behavior is undefined -- you could only wish that it
crashed dependably.

Fortunately, if you use RAII, you rarely have to worry
much about it.

Undefined behavior, but every time I've done it I've had a crash (luckily).
If you set the pointers value to 0 (or NULL) after you delete it nothing
happens, this is allowed.
