What issue is cause when trying to update an author's information in the struct storage method used in the lab?

The Author array was static and could not be changed.

The author array needed to be resized, which is slow.

Only one instance of that author is updated.

The memory for the author would leak.

There was no problem

$2$

$50$ points

Does the following function have a memory problem?

int $*$ fun$($int n$)\{$

if $($n

return NULL;

$\}$

int $*$ tmp;

tmp $=$ malloc$($sizeof$($int$)*$ n$)$;

$*$tmp $=7$;

return tmp;

$\}$

No

Yes
