$1.(6$ points$)$ Consider the code below:

$1$ # include $<$ stdio $.$h $>$

$2$ # include $<$ stdlib $.$h $>$

$3$

$4$ struct db$\_$entry $\{$

$5$ char $*$ name ;

$6$ char $*$ value ;

$7\}$;

$8$

$9$ void dbe$\_$print $($ struct db$\_$entry $*$ entry $)$

$10\{$

$11$ fprintf $($ stdout $,"\%$s $=>\%$s

$",$ entry $->$ name $,$ entry $->$ value $)$ ;

$12\}$

$13$

$14$ int main $($int argc $,$ char $**$ argv $)$

$15\{$

$16$ struct db$\_$entry $*$ e ;

$17$ e $->$ name $="$ hocus pocus $"$;

$18$ e $->$ value $="$ focus $"$;

$19$ dbe$\_$print $($ e $)$ ;

$20$ return $0$;

$21\}$

This code compiles, but crashes when it is run. Suspecting a problem with dbe print,

you comment out the line of code that prints the entry $(11),$ however the program still

crashes! You suspect the crash is caused by a memory allocation problem.

$($a$)$ What is the reason for the crash?

$($b$)$ Without changing existing code, you can solve this problem by inserting additional

code to correct the crash and resolve the memory issue.

Indicate what code you would insert and the line numbers immediately before

where your code will be inserted. $($For example, $$insert this code after line $19$ or

$$insert this code just above line $9.)$
