Stack smashing question in C$.$

Given the following C code file, perform a stack smash on the $($vuln$.$c$)$ code file using a C program that you create named $`$exploit$.$c$`.$ Your program should attempt to open up a reverse shell on the attacked program as root by exploiting the buffer $($you can verify this by typing the command $`$whoami$`$ on the resulting terminal$).$ The $($vuln$.$c$)$ code must be compiled in its own, separate program and must not be altered from its original state.

#include

int main$($int argc, char $**$argv$)\{$

$//$ Make some stack information

char a$[100],$ b$[100],$ c$[100],$ d$[100]$;

$//$ Call the exploitable function

exploitable$($argv$[1])$;

$//$ Return: everything is OK

return$(0)$;

$\}$

int exploitable$($char $*$arg$)\{$

$//$ Make some stack space

char buffer$[10]$;

$//$ Now copy the buffer

strcpy$($buffer$,$ arg$)$;

printf$("$The buffer says $..[\%$s$/\%$p$].$

$",$ buffer, &buffer$)$;

$//$ Return: everything fun

return$(0)$;
