Problem $2(2$ points$).$ Given the stack of the program $($string$\_$vul.c$),$ which we discussed in

our lectures and has format string vulnerability, assume we know the address of int var starts from

$0$xbffff $308$ and the value of it is $0$x$11223344.$

Fig. $1.$ Stack of the program string$-$vul.c$.$

If we run the following commands to write a format string into a file named input and run the program

by reading the file, what will happen?

$string$\_$vul $$ input
