Answer 1

write new int (1) instead of NULL; and check.

Answer 2

1 and Null are different things
Output:
p and &p show pass to this variable
*p is name variable
new int - memory allocation to this variable
Also 0 and Null are different things
0- variable value
Null- empty variable
delete- make variable emty
