Answer 1

logically speaking, the line 1 is more appropriate, since you're check "p" first (p may contain NULL) before the second sub expression gets called. ( as the "&&" operator is part of short-circuit evaluation. thus, will guarantees that the second sub-expression will never be called if the first sub-expression evaluates to false)

Answer 2

Both lines are statement so you should keep in comment.

Answer 3

If there is no difference between the lines then first erase line 1 and find output and then erase line 2(keeping line 1) and find the output both will be different even after line 1 and 2 are same.. I want to know this.. Why this happened..

Answer 10

There are two lines marked as //line 1
&//line 2,first erase the statement marked as //line 1(notice output) now,
(Press back again come to code via link) this time erase the statement marked as //line 2(notice the output)..
Both are different
